Modal Analysis of Gear Considering Temperature Based on ANSYS

Abstract:

In this paper, regarding a spur gear as the object, the natural characteristics under thermal effect are calculated by using ANSYS. Firstly, taking the friction heat and convection heat as the thermal loads, the gear is analyzed under a steady state temperature. Secondly, taking the thermal stress into account, the natural frequencies are calculated. Comparing the natural frequencies between change and without change of temperature. The result of this study shows that the thermal stress produced by the variation of temperature is the main reason of natural frequency change.
