齿轮齿条转向器的CAD/CAE仿真设计
|
摘要
齿轮齿条转向器的结构简单、紧凑,同时兼具较高的传动效率。文章以转向器上的齿轮齿条为研究对象,在Solidworks中建立齿轮齿条啮合的装配模型,在动力学仿真分析软件ADAMS中建立虚拟样机模型,分析机构的碰撞模型;最后,在ANSYS中对模型进行静力学与模态分析,仿真结果可得到应力应变与疲劳寿命等的分布情况,为转向器的实际力学性能评估提供参考依据。
The rack-and-pinion steering gear has simple structure, compact structure and high transmission efficiency. In this paper, the gear and rack on steering gear are taken as the research object, the assembly model of gear and rack meshing is established in Solidworks, the virtual prototype model is established in ADAMS, and the collision model of mechanism is analyzed. Finally, the static and modal analysis of the model is carried out in ANSYS, and the stress response can be obtained by the simulation results. The distribution of variation and fatigue life provides a reference for the evaluation of the actual mechanical properties of steering gear.
