| 摘要: |
| 为解决汽车悬架运动学特性参数优化难题,提出用数学语言描述悬架运动学特性参数的约束条件,及利用牛顿迭代法进行优化的方法.该方法能快速找出所需调整的设计变量,并能快速有效地搜索到最优解,适合于多设计变量、多目标函数的优化.针对某样车后悬架前束角及外倾角存在的问题,应用该方法对目标函数影响较大的设计硬点坐标值进行优化.结果表明,2次迭代后,使悬架运动学特性达到较为合理的设计状态. |

| Abstract: |
| To solve the problem of optimization of vehicle suspension kinematics,a new method to describe the kinematics constraint conditions by mathematics and to optimize the kinematics parameters by Newton iteration method is presented. With it,the proper variable of the suspension and the optimum solution can be found quickly,so that it is suitable to the optimization of suspension kinematics with multi-variable and multi-objective function. Taking a off-road vehicle’s problem in toe angle and camber angle as an example,the optimization results of hard-points coordinates show that the desired characteristics of the suspension kinematics can be achieved in two step iterations. |
