This book was released on 2017 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suspension has been the most important subsystem of the vehicle viewed as a system. The ride comfort and vehicle handling performance are affected by the suspension design. Automotive technology has been continuously incorporating developments over the past few decades to provide the end users with a better comfort of driving. Multi-objective optimization of MR damper with objective function of maximizing damping force generated by MR damper with the geometrical parametric constraint function is achieved in this research using pattern search optimization technique. Research focuses on design, modeling, and simulation of active suspension using non-linear theory of the Magneto-Rheological (MR) damper with consideration of the hysteresis behavior for a quarter car model. The research is based on the assumption that each wheel experiences same disturbance excitation. Hysteresis is analyzed using Bingham, Dahl's, and Bouc-Wen models. Research includes simulation of passive, Bingham, Dahl, and Bouc-wen models. Modeled systems are analyzed for the six road profiles, including road type C according to international standards ISO/TC108/SC2N67. Furthermore, the comparative study of the models for the highest comfort with less overshoot and settling time of vehicle sprung mass are executed. The Bouc-Wen model is 36.91 percent more comfortable than passive suspension in terms of damping force requirements and has a 26.16 percent less overshoot, and 88.31 percent less settling time. The simulation of the Bouc-Wen model yields a damping force requirement of 2003 N which is 97.63 percent in agreement with analytically calculated damping force generated by MR damper. PID controller implementation has improved the overshoot response of Bouc-Wen model in the range of 17.89 percent-81.96 percent for the different road profiles considered in this research without compromising on the settling time of system. PID controller implementation further improves the passenger comfort and vehicle ride handling capabilities. The interdisciplinary approach of systems engineering principles for the suspension design provides unique edge to this research. Classical systems engineering tools and MBSE approach are applied in the design of the MR damper. Requirement traceability successfully validates the optimized MR damper.
Book Synopsis Dynamic Characterization of a Magneto-rheological Fluid Damper and Synthesis of a Semi-active Suspension Seat by : Xiaoqing Ma

This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the point of view of suspension damper, semi-active dampers with only minimal power requirement could be applied to achieve variable damping to enhance suspension performance under complex vibration and shock environments. Magneto-rheological (MR) fluid based dampers offer significant potential for realizing semi-actively controlled variable damping with only minimal power. The MR-fluid dampers invariably exhibit considerable hysteresis, while the damping force varies with the intensity of applied electro-magnetic field and the nature of vibration in a highly nonlinear manner. A simulation model based on symmetric and asymmetric sigmoid functions is developed to fully characterize the properties of a MR-damper as function of excitation and control current. A comprehensive laboratory test program is undertaken to characterize the damping properties of a MR damper under wide ranges of excitations and control current. The essential fundamental features are identified for the modeling task, while the model parameters are identified using multi-parameter error minimization techniques. The validity of the proposed generic model is thoroughly examined by comparing the model response with the measured data under a wide range of excitations, particularly the force saturation and the hysteresis behaviour. An independent current function is further derived that could be integrated to reported regression-based hysteresis models to enhance their prediction abilities. From the results of the study, it is concluded that the refined Bouc-Wen and the proposed generalized sigmoid function model can fully characterized the nonlinear MR damping behaviour as function of applied current and excitation. A nonlinear analytical model of a pneumatic suspension seat including the motion limiting stops is developed for synthesis and analyses of the MR-damping control algorithms. The validity of the passive suspension seat model is thoroughly examined under various deterministic and random vibration excitations of varying intensities. The results suggest that attenuation of shock as well as vibration imposes difficulties design compromise of the passive damper. Owing to the strongly nonlinear properties of the suspension-seat and the MR-damper, such as hysteresis, saturation and end-stop impacts, a 'hi-lo' semi-active control algorithm is synthesized to realized modulation of the control current and thus the damping force following the skyhook control law. A continuous modulation function is further synthesized and integrated to ensure smooth transition between the 'hi' and 'lo' states. A relative position control is further introduced to limit the frequency and severity of shock motions caused by end-stop impacts. A set of performance measures is proposed to assess the characteristics of the semi-active and the resulting integrated controller under a wide range of excitations, including deterministic excitations of continuous and transient nature and random excitations of different vehicles. The potential performance benefits of the controller design are further investigated through a hardware-in-the-loop test and simulation program. The results are used to demonstrate the validity of the MR-damper and suspension seat models, and effectiveness of the control algorithm.

Book Synopsis Semi-active Suspension Control by : Emanuele Guglielmino
Download or read book Semi-active Suspension Control written by Emanuele Guglielmino and published by Springer Science & Business Media. This book was released on 2008-05-27 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semi-active Suspension Control provides an overview of vehicle ride control employing smart semi-active damping systems. These systems are able to tune the amount of damping in response to measured vehicle-ride and handling indicators. Two physically different dampers (magnetorheological and controlled-friction) are analysed from the perspectives of mechatronics and control. Ride comfort, road holding, road damage and human-body modelling are studied. Mathematical modelling is balanced by a large and detailed section on experimental implementation, where a variety of automotive applications are described offering a well-rounded view. The implementation of control algorithms with regard to real-life engineering constraints is emphasised. The applications described include semi-active suspensions for a saloon car, seat suspensions for vehicles not equipped with a primary suspension, and control of heavy-vehicle dynamic-tyre loads to reduce road damage and improve handling.
