摘要:
首先通过大量的交流接触器样本实验,在标准消声室中分别使用传声器、加速度传感器和声级计提取振动噪声信号; 然后,采用零阶声源模型构建交流接触器的标准声辐射指数信息库,并对标准声辐射指数信息库修正; 最后,通过测振法开发交流接触器运行噪声在线测量系统.测试结果表明:基于测振法在线测量系统和声级计测量结果误差为±1.5dB,重复性误差为±1dB,测量结果不受背景噪声影响.
Abstract:
First,the vibrational noise for AC contactor is obtained using the sensors including microphone,accelerator,and sound level meter in the standard anechoic chamber by a lot of sample experiments.Second,the information database of acoustic radiation exponent for AC contactor is built using the zero-order sound source model,and the information database of the standard acoustic radiation exponent is corrected.Finally,based on the oscillometric method,an online measuring system of running noise for AC contactor was developed.The testing results have shown that the measuring error between using the oscillometric method and using the sound level meter is ±1.5 dB,the repeatability error is ±1 dB,and the measuring results were not influenced by the background noise.
