Kinetic Analysis and Optimization of Vertical Leaf Spring Type Independent Suspension and Integral Steering System
Aiming at the problems of motion interference and tire wear in the driving process of automobile suspen-sion system and steering system,based on the rigid body kinematics model of an automobile front suspension and integral steering system,this paper uses the three-dimensional space coordinate transformation method to analyze and calculate the position parameter changes of the key points of the system and the important linkage,and takes the minimum difference between the actual inner and outer front wheel angle relationship and the ideal Ackerman angle relationship as the goal.Based on the integrated simulation technology of iSIGHT and MATLAB,the design variable DOE analysis and optimiza-tion calculation are carried out.After comparative analysis,the optimized design scheme can effectively reduce tire wear and improve the driving performance of the automobile.
