采用ANSYS-Workbench的机械软启动变速器行星架的结构设计

Optimization design of planetary carrier for mechanical soft-start transmission

针对一种新型机械软启动变速器的行星架结构可靠性问题,利用有限元分析方法对其进行可靠性设计。通过对行星架结构的研究,首先构建力学模型,然后通过受力分析,确定边界条件,最后用ANSYS-Workbench分析软件对其结构尺寸进行可靠性设计,通过生产实际检验,证明改进设计后的行星架结构可靠性有了较为显著的提高。

For the reliability problem of planet frame structure in a new type of mechanical soft -start transmission ,did the reliabil-ity improved design based on the finite element analysis method .By the research on the structure of the planet carrier ,built the mechanics model at first ,then determined the boundary conditions after the analysis of stress ,finally improved the structure size using ANSYS-Workbench analysis software .The production practice shows that structure reliability of the planet carrier improved has been remarkably increased .
