摘要
以与某汽车齿轮齿条式转向器配用的转向传动机构为实例,在传统的转向系设计中引入Proe软件建立断开式式转向梯形机构的三维运动实体分析模型,并利用MATLAB中的最小二乘法进行转向梯形的优化设计。通过对比了优化前后的特性曲线,表明优化之后的转向梯形使车轮在转向时左右车轮转角更加符合理论转角关系,从而降低了轮胎磨损,提高的行车平顺性和安全性并更好的保证汽车转弯时车轮作无滑动的纯滚动运动。
Using a motor vehicle rack and pinion steering gear with the steering linkage as an example,bringing the software Proe into the traditional design of the steering system,which to build a three-dimensional motion analysis model of entities of the disconnected steering trapezoid body.And during it,using the least-squares method of the MATLAB to optimizes the design of steering trapezoid.By comparing optimization characteristic curve,it＇s showed that,after optimization,the wheels turn the corner at about the relationship more in line with theoretical angle,which reduces tire wear and improve the driving comfort and safety as well as a better guarantee car turns the wheels to make non-slip pure rolling motion.
