Gear mesh stiffness is an important parameter in the study of gear dynamics, and it is of great significance to accurately calculate gear mesh stiffness. The numerical analysis method is a common method for calculating the meshing stiffness of gears because of its simplicity. Numerical analysis methods include the Ishikawa formula method and the Weber energy method. In this paper, based on two numerical analysis methods, taking the involute spur gear as the research object, Matlab is used to calculate the comprehensive time-varying meshing stiffness of the two methods, and the results are compared and analyzed. The results show that the calculation accuracy of the Weber energy method is higher, which is closest to the results of the finite element method, but the calculation is more complicated. The Ishikawa formula method is more quickly calculated, and the Ishikawa formula method can be prioritized when the gear structure is simple.
