Simulation Study on Vibration Noise of High-speed Electric Drive Gears Based on Recurdyn

为解决常规齿轮振动噪声仿真方法存在误差较大的问题,提出基于Recurdyn的高速电驱动齿轮振动噪声仿真研究。通过Recurdyn软件构建仿真模型,对不同类型的噪声信号进行包络叠加,采用马赫系数等方法划分噪声源分布区间,明确振动噪声分布情况,并获取噪声激励向量数据进行仿真计算。实验结果表明,该方法能够有效减小仿真误差,准确预测齿轮振动噪声声压级。

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.
