摘要
采用近场测量法,绘制了某斯特林发动机表面的噪声等值线图,对关键部位的振动和噪声信号作了相干性分析。实际应用表明,相干性分析用于斯特林发动机的噪声源识别是可行的,具有工程实用价值。
Using near-field measurement to draw the noise contour map of one model of stifling engine surface. Coherent analysis is carried out on vibration and noise signals of key components. The feasibility of coherent analysis used in noise source identification of stirling engine is proved in practice, which shows good engineering utility values.
