摘要: 基于对齿轮强度的理论分析与计算,采用有限元分析软件ANSYS对某工程车辆变速器高速档齿轮进行静力学分析,通过对齿轮静态弯曲应力的有限元计算,验证该高速档齿轮是否满足变速器齿轮强度要求.运用FE-SAFE软件进行齿轮疲劳寿命分析,并通过ANSYS得到齿轮的疲劳寿命云图,结果表明该变速器高速档齿轮弯曲疲劳寿命是满足要求的.

关键词: ANSYS, 静态弯曲应力, 有限元, FE-SAFE, 疲劳寿命

Abstract: A finite element analysis software-ANSYS has been used to analyze the static strength of a helical gear pair of the off-road Vehicle transmission,which is based on the theoretical calculation of the transmission gear strength.Whether the strength of the transmission gear of meets the requirements could be verified by the finite element calculation of the static bending stress of the transmission gear.Combining FE-SAFE software to complete the analysis of gear fatigue life,and the fatigue life figure could obtaioed using ANSYS.Results show that the gear bending fatigue meets the requirements.

Key words: ANSYS, static bending stress, finite element, FE-SAFE, fatigue life
