Abstract: Suspension system plays a very important role in a car, determines the vehicle handling stability and ride comfort. In order to make the preliminary design of the double wishbone independent suspension performance improved, therefore, the front suspension is optimized by multi-objective topology optimization method. Firstly, established the template subsystem of front suspension system of the existing vehicle in ADMAS/CAR, the change curve of wheel positioning parameters were simulated. Then, in the ADAMS/Insight module, the design goal was wheel positioning parameter, the design variable was the front suspension hard point coordinate, depending on the sensitivity, optimized the hard point coordinates of the front suspension, curve comparison results show that the optimization is effective.
