周期对称性在结构分析中的应用

摘要

In engineering practice,cycle symmetrical structure is very common.The calculating model of the basic sector of a gear of mine hoist decelerator taken as an example in the paper.The calculated results are extendedly analysed by finite element analysis.Thus we not only reduce the computional scale,but also improve the computational efficiency.It can provide a reference for the finite element analysis of the similar structure.%在工程实践中周期对称结构非常常见,文中以某型矿井提升机减速器齿轮为例,运用ANSYS软件建立起该齿轮单个基本扇区的计算模型,并进行有限元分析计算,进而在通用后处理器中扩展分析计算结果,即减小了分析规模、又提高了计算效率,可为类似结构的有限元分析计算提供参考.
