Research on the Fatigue Strength for Involute Linear Cylindrical Gear Based on Sensitivity Analysis

This paper Adopt Latin Hypercube Sampling as input and use the five interpolation numerical differential method to deal with output according to the mathematical model of fatigue strength for gear,then get the sensitivity values from structural parameters of gear to fatigue strength.And Find out the influence law and sensitive degree of structural parameters of gear to fatigue strength.The study provides important theoretical basis for gear’s parameters optimization design,and it’s also helpful for other mechanical transmission device’s sensitivity research.
