摘　　要：在进行负载工况下的电动机噪声测试时,负载噪声与被测负载产生的噪声较难分离。阐述了采用振速法测定电机负载噪声的测试机理及原理模型,介绍相关的测试方法,提出了振速法测定电机负载噪声声功率级的测试过程及注意事项。It is difficult to separate the load noise from the noise generated by the measured load when the motor noise is tested under the load condition.The test mechanism and principle model of vibration velocity method for measuring motor noise under the load condition and relevant test methods are illustrated,and the test process and matters for attention of vibration velocity method for measuring noise sound power level of motor under the load condition is proposed.
