Solving time-varying mesh stiffness of spur gears based on improved potential energy method

Journal of Mechanical Engineering, Automation and Control Systems
Meshing stiffness is an important factor in gear dynamics analysis. At present, there are many ways to calculate the meshing stiffness of gears, and we usually use the potential energy method to solve and calculate the meshing stiffness of healthy (faulty) gears.
