The helical gear system is an important form of transmission in high-speed trains. The wear fault parameters of a bending-torsion-shaft coupling mode with six degrees of freedom are established. Using the variable step fourth-order Runge-Kutta numerical integration method, the gear dynamics model with fault parameters is analyzed to get the dynamic response of the helical gear system. The periodic motion and so on with variable fault parameters are analyzed qualitatively based on the results.
