在齿轮研究中,边界单元法(B. E. M.)是一种非常有利的应力分析方法。因为必须离散的仅仅是物体的轮廓,所以计算机输入信息较之有限单元法大为减少,因而使分析费用降低。本文目的在于把它和一些最重要的齿轮分析方法相比较,进而对B. E. M.进行评价。为此,选择了不同齿轮付的有效的决疑法;编制了分析工具——前处理和边界单元法弹性静力分析程序;完成了B. E. M、AGMA、ISO、KELLEY以及ALMEN等方法的分析,并将结果进行了比较。比较中考虑了若干参数,诸如危险断面位置、最大应力比等。最后,进行了重要的讨论并且得到了有关结论:无论是结果的精度方面,还是从经济观点来看,B. E. M.都不愧为一种行之有效的方法。
In the gear research, the boundary element method (B. E. M.) is a very favorable stress analysis method. Because only the outlines of the objects must be discrete, the input to the computer is greatly reduced compared to the finite element method, reducing the cost of the analysis. The purpose of this article is to compare it with some of the most important gear analysis methods and to evaluate B. E. M. In order to do this, we choose the effective method of determining the number of gears, formulating the analysis tool, pre-processing and boundary element method, elastic static analysis program, analyzing the methods of BE M, AGMA, ISO, KELLEY and ALMEN, The results were compared. Several parameters are considered in the comparison, such as the location of the dangerous section, the maximum stress ratio, and the like. Finally, there was an important discussion and the relevant conclusion was reached: B. E. M. deserves to be an effective method, both in terms of the precision of the results and from an economic point of view.
