RESEARCH OBJECTIVE: Automobile Industry has driven through the ages with continuous development with innovative technologies and frugal engineering. Expectation of customer is also increasing through the generations. To meet the customer demand for performance and be best in market, OEM needs to deliver best performance of vehicle with cost effective and short development process. Steering and Handling of vehicle is one of major customer touchpoints and needs to be tuned to achieve various conflicting requirements. The objective of this research is to optimize the steering and handling using correlation between three major methods of evaluation. METHODOLOGY: Methodology for optimization of steering and handling performance using correlation between subjective evaluation, objective measurement and multi-body-dynamic simulation is presented. In first phase, correlation of objective steering & handling parameters is established with subjective evaluation, based on evaluation of various vehicles in SUV segment. The objective parameters which give highest correlation are selected for target setting process. In second phase, Multi-body dynamic(MBD) model is developed in MSC ADAMS and is validated through physical kinematic and compliance data. Components such…
