Analysis of Nonlinear Dynamics Characteristic of Spur Gear Pair System with Fault

Jixie chuandong, 2019
The nonlinear dynamics model for a spur gear pair system is established where the mild wear and crack faults are considered. The nonlinear dynamics equations with faults are solved by employing 4~5 order variable step size Runge-Kutta method.
