摘要
利用UG NX软件建立某客车双横臂独立悬架转向系统模型。基于NX CAD/Motion/Natran协同仿真平台,对转向系统结构进行系统动力学仿真,绘制前束角变化曲线,同时对内、外侧前轮转向角关系仿真曲线与阿克曼理论曲线进行对比分析。运用NX/Nastran与NX/Motion共同建立刚柔混合模型并对转向节臂进行柔性分析和拓扑优化。
In this paper, UG NX software is used to establish the model of Ackerman steering linkage of certain coach' s doublewishbone independent suspension. Based on NX CAD/Motion/Nastran co -simulation platform, the system dynamics simulation of the steering system is performed. The toe - in Angle change curve is drawn, and relationship simulation curve of inner and outer front wheel steering angle is compared with Ackerman theoretical curve. Using the NX/Nastran with NX/Motion, rigid -flexible coupling model is established and the Knuckle arm flexibility analysis and topology optimization are performed.
