摘　　要：文章采用解析法推导了前桥内外轮之间的转角关系,并以梯形臂长m,梯形底角q为优化变量建立优化方程,最后并应用MATLAB软件编制了"转向梯形机构优化设计"程序,对某双前桥载货车转向梯形进行了优化,优化结果显示优化效果明显,达到了设计目的。In this paper, the turning angles relationship of the internal and exernal wheels in the first axle was gotten in analytic method. And the optimization equations were established by the length of steering trapezium arm m and steering trapezium cornerq. Then the program about the optimization of steering trapezium structure was written with MATLAB and emulated for the steering trapezium of double front axle truck. The result was improved obviously after optimization.

关 键 词：双前桥 转向梯形 转角关系 优化
