Due to large errors in simulation methods for the conventional gear vibration noise,a high-speed electric drive gear vibration noise simulation study based on Recurdyn was proposed.The simulation model was built based on Recurdyn software,envelope superposition on different types of noise signals was performed,methods such as the Mach coefficient were used to divide the distribution interval of noise sources,the distribution of vibration noise was clarified,and noise excitation vector data for simulation calculation was obtained.The experimental results showed that this method can effectively reduce simulation errors and accurately predict the sound pressure level of gear vibration noise.
