Abstract: To study the influence of the temperature on the gear structure mode, modal analysis of gear was done based on the coupled thermalstructural analysis. By comparing the modal analysis results under different working conditions, the influence of temperature field on the gear mode was analyzed. Monte Carlo simulation of the probabilistic design method was performed on the gear resonance reliability sensitivity with considering the factor of temperature field. The results showed that the changes of the material mechanical properties caused by temperature change have different impact on each order natural frequency, whose variation caused by thermalstress is smaller than that caused by mechanical property change. Among all random variables, gear module has the greatest impact on the resonance reliability. The results agree well with the actual working conditions. The work initiates a new idea in the field of gear reliability design.
