Simulation of Dynamic Matching and Fatigue Damage of Helical Gear

In order to meet the operating requirement, the precision design and machining for the helical gear are made. Nonlinear finite element simulation software MSC Marc is used to calculate the surface contact stress and bending stress of the gears. The flexible life of the helical gear is also got with software MSC Fatigue. In the end, safe life factor is received according to the design life and is a gist for helical gear design.
