Simulation of Time-Varying Gear Mesh Stiffness Calculation

This paper presents a simulation program designed for calculating time-varying gear mesh stiffness. The program incorporates dynamic stiffness variation algorithms, enabling more accurate simulation of gear transmission operation during the stiffness calculation process. Specifically, the implementation includes numerical integration methods and finite element analysis approaches to model stiffness changes over time. After prolonged operation, gear transmission systems experience changes in mesh stiffness due to factors like wear, which leads to increased transmission errors. The simulation employs time-step iteration algorithms and stiffness update functions to dynamically adjust stiffness values at each calculation interval. Therefore, incorporating time-varying mesh stiffness in the simulation program is essential for realistic modeling. The program can analyze various types of gear transmissions through parametric configuration modules and generates corresponding stiffness calculation results using data visualization components. Key functions include mesh stiffness calculation algorithms, wear progression modeling, and error analysis routines. This effectively assists engineers in designing more stable and reliable gear transmission systems by providing accurate dynamic stiffness characteristics through computational simulation methods.
