The prediction of vehicle handling performance adds to several important inputs to the suspension designers early in the stage of product development. These inputs, for instance, the cornering behavior and lane change performance, provide better understanding to propose the suspension specification [1,2]. In this paper, a concept study for vehicle handling performance of a test vehicle between the rear suspension setup of semi-independent trailing arm and torsion (twist) beam in the same platform using computer aided engineering (CAE) techniques has been carried out. Here, a full CAE vehicle model in ADAMS/Car has been developed and standard vehicle handling performance tests are simulated. The CAE test results are validated with that of physical testing performed on a proto vehicle and correlation is established.

In a highly competitive global as well as the domestic market of the passenger car industry, the search for the complete car is on the forefront. With such a situation, carmakers are experimenting with innovative technology on various development programs to cater the needs of the customer. This paper shows one such experimentation to extract the basic suspension Kinematics & Compliance data with the integration of a Tri-axial Spindle Coupled road load simulator, a wheel force transducer and a Wheel Vector Sensor in absence of expensive Suspension Parameters Measuring Machine (SPMM).
