Optimization of Positioning Parameters for McPherson Front Suspension Based on ADAMS/Car

A virtual prototype model of a McPherson front suspension is built that is used of ADAMS/Car and based on multi-body system dynamics and conducted the parallel wheel travel simulation. After sensitivity analysis of suspension design factor and optimization of multiple iterations using ADAMS/Insight, the design factor parameter that has great influence for the optimization goal sensitivity is found under the optimization constraints finally. The problem of suspension positioning parameters optimization is better solved by optimizing the design factor parameters.
