Suspension analysis and optimization of the four-wheel independent drive electric vehicle based on ADAMS
In order to solve the problems of suspension design scheme of traditional fuel vehicle used in electric vehicle,and the problem that the increase of unspring load quality and the change of arrangement of steering system etc.affect the vertical performance of vehicle,taking the front MacPherson suspension of a four-wheel independent drive electric vehicle prototype as an example,the dynamic model of the front MacPherson suspension is established based on the stress analysis and CATIA software.The influence of key points with different coordinate values on ride comfort and handling stability of EV is studied by ADAMS simulation.Four positioning parameters(front wheel toe angle,camber angle,kingpin camber and kingpin inclination angle)are optimized using the characteristics of ADAMS/Postprocessor correlation curves.The results show that after optimization,the minimum change of toe angle is 0.34°,which is increased by 41.5％;the maximum change of kingpin caster angle is 1.1°,which is reduced by 31.4％.
