Research on a Pair Meshing Gear Model Discrete into SPH Particle

利用连续体离散成均匀分布SPH粒子的思路,以渐开线直齿轮为例,通过其各部分曲线进行研究,确定齿轮齿根过渡曲线以及其他部分的参数方程,提出了三维齿轮和一对啮合齿轮模型离散成SPH粒子的方法和算法,编程实现了正确啮合一对齿轮模型离散成SPH粒子的SPH前处理程序。通过用SPH方法对齿轮传动中冲击、接触等问题进行计算和模拟,提供了一种较好的前处理平台。

In this paper,based on continuums discrete into SPH particles idea ,take involute spur gear as an example,the parameter equations of the transition curve of gear root and the other parts of gear are decided by studied every part curve of gear,provide a algorithm of discrete into SPH particles for 3D gear model and a pair of meshing gear model,programmed pre processor program for correct meshing a pair of gear,to calculate and simulate impact ad contact in gear transmission to provide a good pre processor platform.
