Taking the straight bevel gear as research object

using the ANSYS software

in the contact area of the bevel gear meshing

the contact stress analysis is carried out on the gear

the methods of finite element analysis of gear contact is expounded

the analysis of the calculation results is carried out

the equivalent stress distribution graph of gear is acquired. By means of the ANSYS parametric design language（ ANSYS Parametric Design Language

referred to as APDL）

the parametric design finite element modeling and analysis of bevel gear meshing transmission is realized

user interface of bevel gear contact finite element analysis is developed. Compared with the traditional contact stress calculation

analysis model in the process of processing

element type selection and grid

load location and method

parametric design

interface design is reasonable and accurate

the analysis results are correct

consistent with the actual situation

apply static contact in engineering practice to calculate the stress of gear.
