摘要
目的 识别某军用柴油机噪声源 .方法 采用频谱分析法对柴油机作噪声源识别 .结果 获得了柴油机噪声的频谱曲线 ,掌握了引起噪声的主要振动部位及原因 .
Aim\ To identify the noise sources of a military diesel engine. Methods\ The frenquency analysis is used to identify the noise sources for a military diesel engine. Results\ The frenquency response curves of the noise for a military diesel engine are obtained,and the main part causing noise is known. Conclusion\ The frenquency spectrum analysis is valid to identify the noise sources for military diesel engines.
