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。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 algorithm toolbox.Steering error and kinematics propoerty before and after optimization were compared.The result shows that optimal effect of the proposed method is obvious.The method can be used to get optimal suspension and steering system parameters.
