摘　　要：针对汽车悬架系统与转向系统在汽车行驶过程中存在运动干涉、轮胎磨损等问题,本文基于汽车前悬架与整体式转向系统刚体运动学模型,采用三维空间坐标变换法对系统关键点以及重要杆系的位置参数变化进行了分析与计算,并以实际内、外前轮转角关系与理想阿克曼转角关系存在差值最小为目标,基于iSIGHT与MATLAB集成仿真技术,进行设计变量DOE分析与优化计算,经过比较分析,优化后的设计方案可有效降低轮胎磨损,提升汽车的行驶性能。Aiming at the problems of motion interference and tire wear in the driving process of automobile suspension 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 optimization calculation are carried out.After comparative analysis,the optimized design scheme can effectively reduce tire wear and improve the driving performance of the automobile.
