Transient dynamic finite element analysis and reliability assessment of mining excavators gear transmission system

A transient dynamic finite element analysis and reliability assessment of mining excavators gear transmission system is conducted in this paper. Specifically, Transient dynamics method is used in mining excavator transmission gear contact finite element simulation analysis, studying the time-varying gear contact stress. Gear transmission three-dimension modeling was set up using UG software and imported into ANSYS for simulation analysis. According to the distribution of the motor power, and rotational speed, get the gear contact stress distribution, then depending on the materials of the gear tooth surface contact fatigue strength distribution, and get the gear contact fatigue reliability.
