摘要
通过对液压挖掘机机外辐射噪声数值及频谱的分析,找出各个噪声源对整机机外辐射噪声贡献值的大小,甄别主要噪声源,为下一步控制整机噪声提供理论依据。
Through the analysis of the external sound power level and frequency spectrum of the hydraulic excavator, this paper finds out the contribution value of each noise source to the machine, and identify the main noise sources, so that it provides the theoretical basis for controlling the noise of the whole machine in the next step.
