摘要
研究对WN齿轮进行接触强度与啮合仿真分析。采用先进的齿轮啮合和接触的计算机仿真分析技术对复杂的空间多点接触的WN齿轮啮合与强度特性进行研究,研究从齿形创成开始,建立啮合模型,采用3维有限元方法计算WN齿轮轮齿弹性变形与接触应力,进行WN齿轮啮合过程的计算机仿真分析。首次提出用法向啮合间隙和Un it分割方法进行接触分析,实践表明方法是非常有效的。研究还针对不同尺度的WN齿轮的实际啮合状况进行了具体的接触应力和接触区域的解析计算,开发了用于该齿轮机构分析的实用软件。
In this study, a three-dimensional finite element method is adopted to analyze the contact state and strength of WN （Wildhaber-Novikov） gears. The analysis of meshing and contact of gears with computerized simulation has made a significant contribution to these gears. The load distribution on the contact zone of mating tooth surfaces has been investigated because of its complexity in modeling. The study starts from tooth generation analysis and then establishes teeth-meshing models. The finite element method is adopted to calculate the elastic deformation of teeth and contact stresses and to simulate tooth-mating processes. It is the first time that normal gap method and unit partitioning method have been introduced into the field of contact analysis. Besides, the study has calculated the contact stresses and zones of WN gear teeth meshing under different loadings. The gears＇ structaral analysis software has been developed.
