基于最小值优化的汽车转向梯形机构优化设计

摘要

The mathematical model of the vehicle steering trapezium is set up ,the implicit function relationship between the internal and external rotation angles in the mathematical model is analyzed by nonlinear minimum optimization method .And the MATLAB fmincon toolbox optimization method is used to solve the plane mathematical model of steering trapezium , the desired result is obtained .%通过对汽车转向系统中的转向梯形机构进行数学建模，使用数学上有约束的非线性最小值优化方法对该数学模型的内、外轮转角之间的隐函数关系进行了分析和求解，得出了整体式转向梯形模型的内、外轮转角的曲线关系。最后，建立了整体式转向梯形优化求解的数学模型，并用优化法对模型进行求解，得出了理想的结果。
