【摘要】 利用动力学分析软件ADAMS,以汽车转向运动学为基础,对某矿用汽车转向四连杆机构进行了参数分析及优化设计。首先分析了转向机构中最小传动角对汽车转向横拉杆作用力的影响。其次,分析了机构底角和转向臂长度两个变量对汽车转向轮转角误差及转向时间的影响。最后,以转向过程中外侧车轮实际转角与理论转角误差最小为目标函数,应用ADAMS软件完成了转向四连杆机构的优化设计。更多还原

【Abstract】 Based on steering kinematics theory,parameters analysis and optimal design are made on four-bar steering mechanism of a mining truck applying ADAMS software.Firstly,forces on steering tie-rod are analyzed when minimum driving angle of steering mechanism is changed.Secondly,steering angle error and steering time are measured when the bottom angle and steering arm length of steering mechanism are varied.Lastly,optimal design of steering mechanism is finished applying ADAMS software,and objective function is minimal error between theoretical steering angle and practical steering angle during steering course.更多还原
