本文提供了一种有摩擦的三维弹性接触有限元分析方法及其前处理和后处理技术并将此法成功地用于处于啮合状态的斜齿轮。和现有的有限元混合法相较,本算法使刚度方程的求解效率提高四倍:功能较全;参虑了齿面的摩擦效应;只需输入少量基本参数即可进行网格数据自动生成,图形自动显示,网格消隐等,计算完毕,可以自动绘制变形网格图、等应力绂、等位移线等。同时,我们所作的处于啮合状态的轮齿密栅云纹试验结果,证实了本文的算法和程序是有效而且可靠的。
This paper presents a friction-based three-dimensional elastic contact finite element analysis method and its pretreatment and post-processing technology and the successful application of this method in the engaged state of the helical gear. Compared with the existing finite element method, the proposed algorithm can improve the efficiency of the stiffness equation by four times: full function, taking into account the friction effect of the tooth flanks. The mesh data can be automatically generated by inputting a few basic parameters, Graphics automatically display, grid blanking, etc., the calculation is completed, you can automatically draw the deformation grid, such as stress 绂, such as displacement lines. At the same time, the results of the tooth-tooth moire moire in the meshing state we have verified that the algorithm and the program in this paper are effective and reliable.
