| 摘 要： | 把双横臂悬架和转向系统作为整体,利用凯恩方法建立系统的多体模型,列写系统的较低序号物体阵列,建立系统运动方程。以转向总误差为目标函数,以三维连续性函数为权重函数建立系统优化模型,用遗传算法作为解算工具,对双横臂悬架和转向系统进行优化研究,并对优化前后转向误差和运动性能进行了对比。结果表明:该方法优化效果显著,可获得较佳的悬架和转向系统参数。

| Abstract: | Based on Kane method and regarded the double wishbone suspension and steering system as an integrated system,its multi-body model of system and array of lower serial number objects were established.Kinematical equations and constraint equations of system were set up.Taking total steering error as the objective function,and taking a 3D continuous function as weight function,optimization model of the system was founded.Double wishbone suspension and steering system was optimized by using MATLAB genetic algori... |
