This U-shaped metal bar connects opposite wheels together through short lever arms and is clamped to the vehicle chassis with rubber bushes. Its function is to reduce body roll while cornering, also while travelling on uneven road which enhances safety and comfort during driving. Design changes of anti-roll bars are quite common at various steps of vehicle production and a design analysis must be performed for each change. So Finite Element Analysis (FEA) can be effectively used in design analysis of anti-roll bars. The finite element analysis is performed by ANSYS. This paper includes pre-processing, analysis, post processing, and analyzing the FEA results by using APDL (Ansys Parametric Design Language). The effects of anti-roll bar design parameters on final anti-roll bar properties are also evaluated by performing sample analyses with the FEA program developed in this project.

INDEPENDENT TORQUE DISTRIBUTION MANAGEMENT SYSTEMS FOR VEHICLE STABILITY CONTROL A Thesis Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Master of Science Mechanical Engineering by Indrasen Suresh Karogal December 2008 Accepted by: Dr. Beshah Ayalew, Committee Chair Dr. Harry Law Dr. Pierluigi Pisu ABSTRACT Vehicle Dynamics Control (VDC) systems, also called Electronic Stability Control (ESC) systems, are active on-board safety systems intended to stabilize the dynamics of vehicle lateral motion. In so doing, these systems reduce the possibility of the driver’s loss of control of the vehicle in some critical or aggressive maneuvers. One approach to vehicle dynamics control is the use of appropriate drive torque distribution to the wheels of the vehicle. This thesis focuses on particular torque distribution management systems suitable for vehicles with independently driven wheels.

    Development of Vehicle Dynamics Tools for Motorsports

    AN ABSTRACT OF THE DISSERTATION OF Chris Patton for the degree of Doctor of Philosophy in Mechanical Engineering presented on February 7, 2013. Title: Development of Vehicle Dynamics Tools for Motorsports. Abstract approved: ______________________________________________________________________________ Robert K. Paasch In this dissertation, a group of vehicle dynamics simulation tools is developed with two primary goals: to accurately represent vehicle behavior and to provide insight that improves the understanding of vehicle performance. Three tools are developed that focus on tire modeling, vehicle modeling and lap time simulation. Tire modeling is based on Nondimensional Tire Theory, which is extended to provide a flexible model structure that allows arbitrary inputs to be included. For example, rim width is incorporated as a continuous variable in addition to vertical load, inclination angle and inflation pressure. Model order is determined statistically and only significant effects are included. The fitting process is shown to provide satisfactory fits while fit parameters clearly demonstrate characteristic behavior of the tire. To represent the behavior of a complete vehicle, a Nondimensional Tire Model is used, along with a three degree of freedom vehicle model, to create Milliken Moment Diagrams (MMD) at different speeds, longitudinal accelerations, and under various yaw rate conditions. In addition to the normal utility of MMDs for understanding vehicle performance, they are used to develop Limit Acceleration Surfaces that represent the longitudinal, lateral and yaw acceleration limits of the vehicle. Quasi-transient lap time simulation is developed that simulates the performance of a vehicle on a predetermined path based on the Limit Acceleration Surfaces described above. The method improves on the quasi-static simulation method by representing yaw dynamics and indicating the vehicle’s stability and controllability over the lap.

Since that time, our department has become nationally recognized as a major source of information relative to police vehicles and their use. It is our goal to provide law enforcement agencies with the information they require to successfully evaluate those vehicles currently being offered for police service. The Los Angeles County Sheriff’s Department is proud to publish this information, via the internet, to all law enforcement agen- cies. Since the inception of our vehicle testing program in 1974, we have continually refined our efforts in this area in order to provide the law enforcement community with the most current information available. During the 1997 model year testing, the Sheriff’s department expanded its existing criteria to include an urban or city street course. This course consists of multiple city block distances punctuated by the various types of turns normally found in most inner city environments. The city street course is designed to simulate the conditions encountered by most officers working in typical urban communities. The test is only conducted on vehicles offered with a factory “police package”.

    Rolling Stability Control Based on Electronic Stability Program for In-Wheel-Motor Electric Vehicle

    Page 0034 World Electric Vehicle Journal Vol. 3 - ISSN 2032-6653 - © 2009 AVERE EVS24 Stavanger, Norway, May 13 - 16, 2009 Rolling Stability Control Based on Electronic Stability Program for In-wheel-motor Electric Vehicle Kiyotaka Kawashima, Toshiyuki Uchida, Yoichi Hori University of Tokyo, Tokyo, Japan, [email protected] Abstract In this paper, a novel robust rolling stability control (RSC) based on electronic stability program (ESP) for electric vehicle (EV) is proposed. Since EVs are driven by electric motors, they have the following four remarkable advan- tages: (1) motor torque generation is quick and accurate; (2) motor torque can be estimated precisely; (3) a motor can be attached to each wheel; and (4) motor can output negative torque as a brake actuator. These advantages en- able high performance three dimensional vehicle motion control with a distributed in-wheel-motor system. RSC is designed using two-degree-of-freedom control (2-DOF), which achieves tracking capability to reference value and disturbance suppression. Generally, RSC and YSC are incompatible. Therefore, ESP, which is composed of estima- tion system(S1) and integrated vehicle motion control system(S2) is proposed. A distribution ratio of RSC and YSC is defined based on rollover index (RI) which is calculated in S1 from rolling state information. The effectiveness of proposed methods are shown by simulation and experimental results.

Received: 16 December 2019; Accepted: 31 January 2020; Published: 14 February 2020 Abstract: The lightweight design of trucks is of great importance to enhance the load capacity and reduce the production cost. As a result, the taper-leaf spring will gradually replace the multi-leaf spring to become the main elastic element of the suspension for trucks. To reveal the changes of the handling stability after the replacement, the simulations and comparison of the taper-leaf and the multi-leaf spring suspensions with the same vertical stiffness for trucks were conducted. Firstly, to ensure the same comfort of the truck before and after the replacement, an analytical method of replacing the multi-leaf spring with the taper-leaf spring was proposed. Secondly, the effectiveness of the method was verified by the stiffness tests based on a case study. Thirdly, the dynamic models of the taper-leaf spring and the multi-leaf spring with the same vertical stiffness are established and validated, respectively.
