Abstract :
To strengthen the parts universality of a series of passenger cars and improve a passenger car ride comfort, the elastic components and the installation location of the vehicles are optimized. The optimization scheme of widening, lengthening the rear suspension leaf spring, and narrowing diameter of the front suspension torsion bar spring are analyzed, then the front and rear suspension stiffness match is done. The optimal passenger car model is built by ADAMS software to simulate, and the weighted RMS acceleration is calculated by MATLAB, the results meet the requirements. Then, the real vehicle test is done, and the comparative analysis of the performance with the original passenger car is done. The results show that, the optimization model´ s ride comfort index than that of the original passenger cars have greatly increased, and comprehensive evaluation of steady static circular is also slightly higher scores.
