Book Synopsis FMVSS 105 Inertia Brake Dynamometer Test Procedure for Vehicles Above 4 540 Kg GVWR by : Truck and Bus Hydraulic Brake Committee
Download or read book FMVSS 105 Inertia Brake Dynamometer Test Procedure for Vehicles Above 4 540 Kg GVWR written by Truck and Bus Hydraulic Brake Committee and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Recommended Practice is derived from the FMVSS 105 vehicle test and applies to two-axle multipurpose passenger vehicles, trucks and buses with a GVWR above 4 540 kg (10 000 lbs) equipped with hydraulic service brakes. There are two main test sequences: Development Test Sequence for generic test conditions when not all information is available or when an assessment of brake output at different inputs are required, and FMVSS Test Sequence when vehicle parameters for brake pressure as a function of brake pedal input force and vehicle-specific loading and brake distribution are available. The test sequences are derived from the Federal Motor Vehicle Safety Standard 105 (and 121 for optional sections) as single-ended inertia-dynamometer test procedures when using the appropriate brake hardware and test parameters. This recommended practice provides Original Equipment Manufacturers (OEMs), brake and component manufacturers, as well as aftermarket suppliers, results related to brake output, friction material effectiveness, and corner performance in a laboratory-controlled test environment.The test sequences include different dynamic conditions (braking speeds, temperature, and braking history as outlined in the FMVSS 105); inertia loads equivalent to the vehicle's LLVW and GVWR; fully operational, partial failure, and failed system conditions. All applicable sections of the FMVSS 105 are included. Optional sections include: parking brake output, water recovery, TP-121D dynamometer retardation, and 32 km/h (20 mph) stops to simulate Federal Motor Carrier Safety (FMCS) requirements.This Recommended Practice does not evaluate or quantify other brake system characteristics such as wear, noise, judder, ABS performance, or braking under extreme temperatures or speeds. Minimum performance requirements are not part of this recommended practice. Consistency and margin of pass/fail of the minimum requirements related to stopping distance or equivalent deceleration levels of the FMVSS 105 vehicle test can be assessed as part of the project in coordination with the test requestor when using the appropriate vehicle information and vehicle dynamics modeling. Nevertheless, this procedure and its results do not replace the vehicle-level test to demonstrate compliance to FMVSS (105 for hydraulic brake systems or 121 for air-over-hydraulic brake systems), or other mandatory regulations (like ECE R13 or equivalents). Vehicle and braking systems development is fast-paced, and involves a global supplier base. This Recommended Practice provides an inertia-dynamometer test procedure that is repeatable and cost-effective. It evaluates the performance of the brake corner and its components (including friction material) by following the test procedure and sequence as indicated in the Federal Motor Vehicle Safety Standard (FMVSS) 105. Data from this Recommended Practice may be combined with other brake system and vehicle characteristics to predict vehicle performance.Since the first release of the FMVSS 105, there have been numerous inertia-dynamometer test protocols developed and used by the industry with different approaches and levels of detail. The SAE Truck and Bus Hydraulic Brake Committee considers laboratory test procedures useful in supporting harmonization to improve the overall performance and safety of motor vehicle braking systems.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Recommended Practice is derived from the FMVSS 105 vehicle test and applies to two-axle multipurpose passenger vehicles, trucks, and buses with a GVWR above 4540 kg (10000 pounds) equipped with hydraulic service brakes. There are two main test sequences: Development Test Sequence for generic test conditions when not all information is available or when an assessment of brake output at different inputs are required, and FMVSS Test Sequence when vehicle parameters for brake pressure as a function of brake pedal input force and vehicle-specific loading and brake distribution are available.

The current version of this Recommended Practice: (a) addresses proper and consistent use of units of measure and numerical values per NIST 811:2008, and (b) clarifies thermocouple location and temperature controls during the test. The technical content, the test conditions, and the test sequences remain unchanged.

Book Synopsis FMVSS 135 Inertia Dynamometer Test Procedure by : Brake Dynamometer Standards Committee
Download or read book FMVSS 135 Inertia Dynamometer Test Procedure written by Brake Dynamometer Standards Committee and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Recommended Practice is derived from the Federal Motor Vehicle Safety Standard 135 vehicle test protocol as a single-ended inertia-dynamometer test procedure. It measures brake output, friction material effectiveness, and corner performance in a controlled and repeatable environment. The test procedure also includes optional sections for parking brake output performance for rear brakes. It is applicable to brake corners from vehicles covered by the FMVSS 135 when using the appropriate brake hardware and test parameters. This procedure is applicable to all passenger cars and light trucks up to 3500 kg of GVWR.This Recommended Practice is the result of an industry effort to develop an inertia-dynamometer test procedure based upon the FMVSS 135 vehicle test. Results from this test provide a laboratory assessment of the brake corner performance. Data from this Recommended Practice may be combined with other brake system and vehicle characteristics to predict vehicle performance. The conditions defined in this Recommended Practice are drawn from FMVSS 135 vehicle test experience. The deceleration levels are not necessarily based on those needed to meet the requirements of the FMVSS 135. This procedure is intended to properly represent the lining conditioning which occurs during an FMVSS 135 vehicle test.

Download or read book FMVSS Inertia Dynamometer Test Procedure for Vehicles Below 4540 Kg GVWR written by Brake Dynamometer Standards Committee and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document derives from the Federal Motor Vehicle Safety Standards 105 and 135 vehicle test protocols as single-ended inertia-dynamometer test procedures. The test sequences enable brake output measurement, friction material effectiveness, and corner performance in a controlled and repeatable environment. This SAE Recommended Practice (RP) also includes optional sections for parking brake output performance for rear brakes. It applies to brake corners from vehicles covered by the FMVSS 105 and 135 when using the appropriate brake hardware and test parameters. The FMVSS 135 applies to all passenger cars and light trucks up to 3500 kg of GVWR. The FMVSS 105 applies to all passenger cars, multi-purpose vehicles, buses, and trucks above 3500 kg of GVWR. This document does not include testing for school bus applications or vehicles equipped with hydraulic brakes with a GVWR above 4540 kg. This revised document takes into consideration new technologies for braking systems like (a) vacuum assist, (b) electric parking brake (EPB), and (c) regenerative braking. The inertia calculation references the latest version of the SAE J2789 to calculate the test inertia, including two methods to reflect the brake blending for the regenerative system. This revision also addresses formatting and grammatical corrections and clarifies items about FMVSS 105, FMVSS 135, or both. Other aspects of the rationale from previous revisions of this SAE Recommended Practice (RP) are still applicable.

Book Synopsis Low-duty Inertia Dynamometer Hydraulic Brake Wear Test Procedures for Vehicles Above 4536 Kg (10 000 Lb) of GVWR by : Truck and Bus Hydraulic Brake Committee
Download or read book Low-duty Inertia Dynamometer Hydraulic Brake Wear Test Procedures for Vehicles Above 4536 Kg (10 000 Lb) of GVWR written by Truck and Bus Hydraulic Brake Committee and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Recommended Practice is derived from OEM and tier-1 laboratory tests and applies to two-axle multipurpose passenger vehicles, or trucks with a GVWR above 4536 kg (10 000 pounds) equipped with hydraulic disc or drum service brakes. Before conducting testing for a specific brake sizes or under specific test conditions, review, agree upon, and document with the test requestor any deviations from the test procedure. Also, the applicable criteria for the final test results and wear rates deemed as significantly different require definition, assessment, and proper documentation; especially as this will determine whether or not Method B testing is needed.This Recommended Practice does not evaluate or quantify other brake system characteristics such as performance, noise, judder, ABS performance, or braking under extreme temperatures or speeds. Minimum performance requirements are not part of this recommended practice. Consistency and margin of pass/fail of the minimum requirements related to wear rates and wear behavior can be assessed as part of the project in coordination with the test requestor.NOTE: This Recommended Practice uses the unit conversion and rounding techniques from the NIST Special Publication 811. This to ensure the use of standard conversion factors and to determine the appropriate number of significant digits to ensure the Rounding Error (RE) of the converted unit is smaller than or similar to the RE of the original English or Imperial unit. Certain vehicle applications (like flat-bed recovery vehicles) have driving patterns which are considered light-duty with (a) friction material temperatures remaining under 232.0 °C (450 °F) 2.03 to 2.54 mm (0.08 to 0.1 inch) below the braking surface for at least 90% of the time, and (b) brake applications which require 2690 kPa (390 lbf/in2) or less of hydraulic pressure. This Recommended Practice provides two inertia-dynamometer test procedures, which are repeatable and cost-effective to assess, screen, benchmark, troubleshoot, or fingerprint a given foundation brake regarding low-duty brake wear. The first procedure (or Method A) is a wear versus temperature test from 93.0 to 427.0 °C (200 to 800 °F) to determine if there are potential wear rate issues under low temperature conditions and a low-duty driving cycle. If deemed required after the initial wear versus temperature test (Method A), or upon direct customer request, the second procedure (or Method B) provides an extensive wear test at a constant temperature of 79.0 °C (175 °F) to determine the wear rates and behavior of the friction couple. Data from this Recommended Practice may be combined with other brake system and vehicle characteristics for a comprehensive product characterization program.Since other wear test procedures cover a different (higher) range of operating temperatures, kinetic energies, and levels, the accelerated wear rate behavior of certain friction materials under low-duty regimes is not properly determined or estimated using test conditions which can affect the transfer layer behavior. The wear test method implemented in this Recommended Practice was derived from prior field testing and correlation investigation. Hence, careful attention was given to not alter the sequence and test conditions which have demonstrated correspondence to the vehicle behavior.The SAE Truck and Bus Hydraulic Brake Committee considers laboratory test procedures useful in supporting harmonization to improve the overall performance, durability, and safety of motor vehicle braking systems using relevant and cost-effective protocols.

Download or read book In-Service Brake Performance Test Procedure Passenger-Car and Light-Duty Truck written by Road Test Procedures Standards Committee and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Recommended Practice establishes a uniform procedure for testing the brake systems (service and parking) of all passenger cars, light-duty trucks, and multipurpose passenger vehicles up to and including 4500 kg (10 000 lb) GVWR. The purpose of the test code is to evaluate brake system performance of vehicles in service for compliance with regulations. The test code is expected to be utilized as a basis for a brake evaluation conducted by State or Federal officials engaged in highway safety programs. The primary consideration is that this test requires a minimum of instrumentation, time, driver skill, and cost to conduct.This document is Cancelled without replacement. FMVSS/CMVSS test procedures define brake performance test procedure. SAE J201 is not used by industry and is being cancelled to prevent use of obsolete standard.

Book Synopsis Brake Dynamometer Squeal Noise Test Procedure for Commercial Vehicles with Air Brakes by : Truck and Bus Foundation Brake Committee
Download or read book Brake Dynamometer Squeal Noise Test Procedure for Commercial Vehicles with Air Brakes written by Truck and Bus Foundation Brake Committee and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Recommended Practice applies to commercial vehicles above 4540 kg of gross vehicle weight rating equipped with air brakes used under normal operating conditions. The procedure incorporates high and low-temperature test matrices, but does not fully account for the effects of the environment on brake squeal. Much research is currently underway in this area. This document defines brake squeal as a peak noise level of at least 80 dB(A) between 500 Hz and 17 kHz for air disc and drum brakes on on-road vehicles. Commercial vehicle (CV) manufacturers and their suppliers need a standard laboratory method to assess the propensity of the foundation brakes to generate squeal noise. The early engineering assessment for noise provides a baseline during the vehicle or brake system development process. This document allows multiple parties to speak to the same parameters when reviewing squeal noise testing and before vehicle evaluations. A systematic squeal noise test procedure supports the entire supply chain for the lifetime of the braking system.
