The results show that the simulation results agree well with the test results , and the correctness of the nonlinear dynamic model and the nonlinear dynamic meshing model is verified . Aiming at the single - stage gear transmission system , under the action of engine excitation , different dynamic models are adopted to analyze the influence law of the engine speed , the center support rigidity and the center distance deviation on the dynamic load . The influence rule of the rotating speed , the clearance and the center distance deviation on the dynamic load in the no - load condition is analyzed . The motion form of the gear transmission system under different conditions is analyzed by combining the qualitative and quantitative analysis methods of nonlinear dynamics . The obtained conclusion can be used to guide the design of the gear transmission system with low vibration and low noise .
