A Method of Reliability Sensitivity Analysis for Gear Drive System
Based on profile involutes equation and tooth easement curve equation of standard gear, parameterization three dimensional finite element model of the gear drive system is built up in ANSYS, and numerical computation of the working process is taken in ANSYS/LS-DYNA, then contact stress of and pressure distribution are got. It creates an ultimate state equation of every system parameter (input) converting to output (response), considering different system random error synthetically, sample points locations in input variable sampling space are fixed with the method of matrix experiment design, which was used in series of deterministic fitting test. In the test, least-squares procedure regression analysis of the ultimate state equation is taken to fix the items and coefficients after multiple fitting test. Using this ultimate state equation, system reliability level and reliability sensitivity of different variables can be calculated which provides theoretical bases for dynamic optimum design of gear drive syste m.
