Time-Varying Stiffness Calculation of Spiral Bevel Gears Based On SIMPACK

Aiming at the difficulty in calculating the time-varying stiffness of spiral bevel gears, the time-varying stiffness acquisition and calculation of spiral bevel gears under the actual coincidence degree based on SIMPACK is proposed. Taking a pair of spiral bevel gears as an example, the process of modeling and simulation with SIMPACK is described in detail. The numerical results are compared with the ISO standard calculation method, which verifies its correctness and rationality. Through the analysis of the relationship between meshing stiffness and load and damping under different working conditions, it is shown that meshing stiffness increases nonlinearly with the increase of load, and load damping makes the change of stiffness curve gentler.
