Abstract

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
