Dynamic simulation of fixed shaft cylindrical gearbox based on rigid-flex coupling model

The gearbox system is a crucial component of mechanical equipment's transmission system, but because of its demanding workload and hostile working environment, it is vulnerable to failure. The typical defect detection approach requires the collection of vibration signals via sensors for analysis, but doing so is expensive and time-consuming. The fixed shaft gearbox rigid-flex coupling model is built in this research using Solidworks, Ansys, and the dynamic simulation program Adams. The motion rule of the gear and the gearbox response characteristics are then derived by simulation. The feasibility and correctness of the model are confirmed by the comparative analysis of simulation data and experimental platform data, providing a theoretical foundation for gearbox problem diagnostics and reliability study.
