摘要
主要研究带有储油孔和螺旋导油槽的防锈螺栓的有限元建模与强度分析,通过有限元计算得到它的承载能力。在有限元软件中采用间接的方法生成螺旋实体,这种实体可以得到质量较好的有限元网格。比较采用渐进失效分析与最大应力准则和不采用渐进失效分析的结果。同时采用折减计算的方法进行模拟,比较折减计算的的结果与没有采用折减计算的结果并进行分析。
In this paper, the main research is the finite element modeling and strength analysis of the anti-rust bolts with oil reservoir and helical groove, and obtain its bearing capacity is by finite element method. In the finite element software, an indirect method is used to build the helical entity, which can obtain the finite element mesh with better quality. Compares the results of the progressivefailure analysis, the maximum stress criterion and the non-progressive failure analysis. Simulates by using the method of reduction calculation at the same time, and compares reduction calculation results and the original results and analysis.
