construction machinery noise

基本解釋

This paper sets up damp control system model based on property of construction machinery vibration and noise.
本文針對(duì)工程機(jī)械振動(dòng)與噪聲特點(diǎn)建立起阻尼控制系統(tǒng)模型，并對(duì)模型參數(shù)特性進(jìn)行了分析；
Damp control is new technology for vibration and noise of construction machinery developed rapidly in recent years.
工程機(jī)械的振動(dòng)和噪聲阻尼控制是近年發(fā)展較快的新技術(shù)。
Engine exhaust noise is a main source for construction machinery noise, and it has a very significant impact on the level of construction machinery noise.
發(fā)動(dòng)機(jī)排氣噪聲是工程機(jī)械整機(jī)噪聲中最主要的噪聲源，對(duì)于工程機(jī)械整機(jī)噪聲水平的高低有重要的影響。
