内燃机机械噪声与燃烧噪声识别
The identification of mechanical noise and combustion noise in internal combustion engine
摘要
Abstract
For identification of Internal Combustion engine(IC engine)noise,a mathematical model is established,and the corresponding procedures ale generated,and the spectrums of the combustion noise and mechanical noise are separated and their Aweighted sound power levels are figured out.Taking example for a single cylinder four-stroke motor,by constructing theoretical examples that include interferential noises to simulate the identification,the accuracy and practicability of the procedures can be validated. Results of identification show that the spectrums of the combustion noise and mechanical noise before and after separation are agreed well.errors of A-weighted sound power level are small.关键词
