内燃机噪声分离试验方法研究

RESEARCH ON THE SEPARATION TEST METHOD OF THE INTERAL-COMBUSTION ENGINE NOISE

本文把声强测量技术应用到内燃机燃烧嗓声与机械噪声分离试验中,推导出燃烧噪声与机械噪声计算公式,提出了一个新的试验方法。

This paper origially applied acoustic intensity measurements to test of distinguishing between combustion noise and mechanical noise of the interal-combustion engine. It derived the formulae of combustion noise and mechanical noise of the engine. An advanced test method was provided.
