Download or read book Modelling and Validation of Agricultural Tire-terrain Interaction written by Mirwais Sharifi and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of Finite Element Analysis (FEA) and simulation software has been extensively used for many engineering applications. More precisely, computerized methods have paved way for accurately simulating tire-terrain interaction. By predicting forces, vibrations, and numerous physical effects, any industry with pneumatic tires can greatly reduce time, cost and effectively design and improve their machinery. The modelling and validation of a High Lug Farm Service (HLFS) agricultural tire is carried out in order to accurately predict tire-terrain interaction. In conjunction with the tire, two agricultural soils are modelled using Smoothed-Particle Hydrodynamics (SPH) method and calibrated to experimental results. An analytical off-road rigid ring model is used to model the HLFS tire's interaction with a surface. The soil dynamics of the HLFS tire running on soil is researched and compared to experimental results. Steering characteristics including self-aligning moment, rolling resistance coefficients, relaxation lengths were obtained under various operating conditions.

Available in PDF, EPUB and Kindle. Book excerpt: One of the key factors for improving the mobility and operating efficiency of trucks is the understanding of the tire-terrain interaction characteristics. Due to the broad range of terrains that trucks may operate over, the understanding process of the tire-terrain interaction is necessary. The terrains for on-road operations are commonly dry or wet surfaces. For off-road operations, a more extensive range of deformable terrains exists, such as dense sand, clayey soil, and gravel. In some cases, vehicles may operate over terrains covered with snow or layers of mixed snow and ice. This research work focuses on modeling and investigating the tire-terrain interaction on several terrains to better predict off-road truck performance. The truck tire used in this research is the off-road Regional Haul Drive (RHD) size 315/80R22.5 drive tire. The truck tire is built node-by-node using Finite Element Analysis (FEA) technique and is validated using different dynamic and static tests that are compared to the manufacturer's measured data. The terrains are modeled and calibrated using the Smoothed-Particle Hydrodynamics (SPH) instead of the classical FEA technique. Furthermore, two soil moisturizing techniques are presented to model moist soils, the virtually calibrated moist sand is validated against physical measurements. The in-plane and out-of-plane rigid ring tire model parameters are calculated for the off-road tire running on various terrains. The tire-terrain interaction is performed under several operating conditions and the effect of the operating conditions are investigated. Furthermore, a detailed study of the rolling resistance coefficient prediction over different terrains is presented. In this research work, the hydroplaning phenomenon is investigated. The hydroplaning speed of the tire is computed under different operating conditions. A novel equation to predict the truck tire hydroplaning speed as a function of several tire operational parameters is developed and validated against an empirical equation. In addition, the rigid ring tire model is integrated into a highly advanced full vehicle model to predict the truck on-road and off-road performance. Nonetheless, in order to validate the simulation results of the truck tire-terrain interaction obtained in this thesis physical testing was carried out in Gothenburg, Sweden by Volvo Groups Truck Technology.

This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant time and cost savings can be realized through the use of virtual simulation of testing procedures across diverse areas of research and development. Fully detailed virtual truck models using the simplified off-road rigid-ring model parameters may further increase these economical savings within the automotive industry. The determination of the off-road rigid-ring parameters is meant to facilitate the simulation of full vehicle models developed by Volvo Group Trucks Technology. This works features new FEA (Finite Element Analysis) tire and SPH (Smoothed Particle Hydrodynamics) soil interaction modeling techniques. The in-plane and out-of-plane off-road rigid-ring parameters are predicted for an RHD (Regional Haul Drive) truck tire at varying operating conditions. The tire model is validated through static and dynamic virtual tests that are compared to previously published literature. Both the in-plane and out-of-plane off-road rigid-ring RHD parameters were successfully predicted. The majority of the in-plane parameters are strongly influenced by the inflation pressure of the tire because the in-plane parameters are derived with respect to the mode of vibration of the tire. The total equivalent vertical stiffness on a dry sand is not as heavily influenced by the inflation pressure compared to predictions on a hard surface. For perspective, at 110 psi, the dry sand total vertical stiffness is nearly nine times smaller than that determined on the hard surface, while the lateral stiffness on soft soil (Dry Sand) is at a minimal of three times higher than that of the corresponding values tested on a hard surface. The cornering stiffness is primarily load dependant because the inflation pressure is only noticeably influential at high vertical loads. More importantly, the soil builds in front of the tire, creating what is called a bulldozing effect, during high slip angles. The additional lateral force of the soil exerted onto the tire during cornering maneuvers may contribute to higher than expected results and may be confirmed through future investigation of the cohesion of the soil model.

Download or read book Deterministic Numerical Modeling of Soil Structure Interaction written by Stephane Grange and published by John Wiley & Sons. This book was released on 2022-01-26 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to describe soil–structure interaction in various situations (nonlinear, static, dynamic, hydro-mechanical couplings), this book gives an overview of the main modeling methods developed in geotechnical engineering. The chapters are centered around: the finite element method (FEM), the finite difference method (FDM), and the discrete element method (DEM). Deterministic Numerical Modeling of Soil–Structure Interaction allows the reader to explore the classical and well-known FEM and FDM, using interface and contact elements available for coupled hydro-mechanical problems. Furthermore, this book provides insight on the DEM, adapted for interaction laws at the grain level. Within a classical finite element framework, the concept of macro-element is introduced, which generalizes constitutive laws of SSI and is particularly straightforward in dynamic situations. Finally, this book presents the SSI, in the case of a group of structures, such as buildings in a town, using the notion of metamaterials and a geophysics approach.

Available in PDF, EPUB and Kindle. Book excerpt: The MIT mission - "to bring together Industry and Academia and to nurture the next generation in computational mechanics is of great importance to reach the new level of mathematical modeling and numerical solution and to provide an exciting research environment for the next generation in computational mechanics." Mathematical modeling and numerical solution is today firmly established in science and engineering. Research conducted in almost all branches of scientific investigations and the design of systems in practically all disciplines of engineering can not be pursued effectively without, frequently, intensive analysis based on numerical computations.The world we live in has been classified by the human mind, for descriptive and analysis purposes, to consist of fluids and solids, continua and molecules; and the analyses of fluids and solids at the continuum and molecular scales have traditionally been pursued separately. Fundamentally, however, there are only molecules and particles for any material that interact on the microscopic and macroscopic scales. Therefore, to unify the analysis of physical systems and to reach a deeper understanding of the behavior of nature in scientific investigations, and of the behavior of designs in engineering endeavors, a new level of analysis is necessary. This new level of mathematical modeling and numerical solution does not merely involve the analysis of a single medium but must encompass the solution of multi-physics problems involving fluids, solids, and their interactions, involving multi-scale phenomena from the molecular to the macroscopic scales, and must include uncertainties in the given data and the solution results. Nature does not distinguish between fluids and solids and does not ever repeat itself exactly.This new level of analysis must also include, in engineering, the effective optimization of systems, and the modeling and analysis of complete life spans of engineering products, from design to fabrication, to possibly multiple repairs, to end of service.

Available in PDF, EPUB and Kindle. Book excerpt: Distributed in the East European countries, China, Northern Korea, Cuba, Vietnam and Mongolia by Academia, Prague, CzechoslovakiaThis book is based on the efficient subsoil model introduced by the authors in 1977 and applied in the last ten years in the design of foundations. From the designer's point of view, the model considerably reduces the extent of the calculations connected with the numerical analysis of soil-structure interaction. The algorithms presented are geared for use on mini- and personal computers and can be used in any numerical method. A special chapter is devoted to the implementation of the model in the NE-XX finite element program package, illustrated with diagrams, tables and practical examples.Besides presenting the energy definition and general theory of both 2D and 3D model forms, the book also deals with practical problems such as Kirchhoff's and Mindlin's foundation plates, interaction between neighbouring structures, actual values of physical constants of subsoils and natural frequencies and shapes of foundation plates.Today, researchers and engineers can choose from a wide range of soil models, some fairly simple and others very elaborate. However, the gap which has long existed between geomechanical theory and everyday design practice still persists. The present book is intended to suit the practical needs of the designer by introducing an efficient subsoil model in which the surrounding soil is substituted by certain properties of the structure-soil interface. When a more precise solution is required, a more sophisticated model form can be used. Its additional degrees of deformation freedom can better express the behaviour of layered or generally unhomogeneous subsoil. As a result, designers will find that this book goes some way towards bridging the above-mentioned gap between structural design theory and day-to-day practice.
