汽车摇臂机构的数学建模及最优化

Mathematical modeling and optimization on rocker mechanism of automobile

运用空间坐标变换理论的有关知识,对双摇臂机构进行运动学分析,建立空间数学模型和基于转向误差最小的最优化模型。考虑车辆的真实行驰状况引入加权函数,从而实现真实工作条件的仿真。最后以一典型车辆为例,验证得出此方法可行且高效。

Utilizing the related transformation theory knowledge of spatial coordinates, kinematics analysis was carried out on the double rocker mechanism and the spatial mathematic model and the optimization model based on the minimum turning errors were established. By introducing the weighted function with the consideration of the real travel status so as to realize the simulation of real working condition. Finally, taking a typical vehicle as an example, it is verified that the obtained method is feasible and with a high efficiency.
