Optimization of Vehicle Handing and Stability Based on RSM
Based on the theory of multi-body system dynamics and simulation software ADAMS/Car,the whole vehicle model was established.Afterwards by means of pylon course slalom,the accuracy of modeling was tested.The analysis and evaluation were later made to draw a conclusion that the handling stability of model needed improved.So as to improve the handling stability,the index lateral acceleration,yaw rate,side slip angle were taken as target function while suspension stiffness parameters were designed variables.Optimization of vehicle handing stability was practiced by applying second-order Response Surface Methodology (RSM) model.The relationship could be obtained by least square method obviously.Moreover applying with linear interpolation the final objective function was decided.The minimum of final objective function was the optimal result.Simulation analysis was performed again for the whole vehicle model by parameters modification.Subsequently,the results showed that this method greatly improved handling stability.
