In projects

the components failure caused by material fatigue almost accounts for 50%

9

0%

and fatigue pitting is the common form of failure in involute cylindrical gear.In the environment of co-simulation with Pro/E

MATLAB

ADAMS and ANSYS

according to the results of gear contact’s static analysis

the weak links can be easily found by loading drive torque of gear in ANSYS

which is extracted in ADAMS actual operating conditions.Using ANSYS fatigue tool module to analyze its fatigue life

the results show that it meets the requirement of the fatigue strength.The research method has a high reference value for the contact analysis of similar components in the structure anti-fatigue evaluation.
