specific Embodiment 1
[0079] A calculation method for dynamic correction of meshing stiffness of spur gears under fluctuating load conditions, comprising the following specific steps:
[0080] Step 1: Use the energy method to synthesize the time-varying mesh stiffness of each pair of transmission gear pairs in the gear transmission system under constant load conditions, calculate the average mesh stiffness of each pair of transmission gear pairs, and substitute the average mesh stiffness into the bending-torsion coupling model of the gear transmission system , load the external fluctuating load to solve the lateral vibration and torsional vibration response of the system, record the lateral vibration response of the nth drive wheel as The torsional vibration response is The lateral vibration response of the nth driven wheel is The torsional vibration response is
[0081] Step 2: Analyze the influence of lateral vibration and torsional vibration response on the actual meshing state of each pa...
