running noise meaning in Chinese
行驶噪声
运行噪音
运转噪音
Examples
- Acceleration running noise level
加速行驶噪声 - Is no gear reduction box , it greatly reduces the running noise and vibration of the car
同时，因为没有轮减速箱运行的噪音及轿厢振动大大减低。 - The high power eletric motor increases the rotary inertia . after balance adjustment , the mechanical viberation and running noise of the rotary parts are remarkably reduced
：采用大功率电机后转动惯量较大，转动零件经过平衡调整后机械震动和转动噪音较以前产品显著减小。 - Due to the complexity of noise prediction calculation , the train running noise was taken as line sound source to predigest the model in fore prediction commonly , by this way , the error of the result and the fact value was relatively great
由于噪声预测计算的复杂性，在以前的预测方法中一般都是将列车运行噪声作为线声源，以使预测模型简化，这样得到的结果与实际值之间误差较大。 - In order to alleviate the problem of railroad noise pollution , this paper studies the wheel - rail noise reducing technology by sticking high damping materials on the two sides of rail according to the characteristics of train running noises after speed increase and wheel - rail noise generating mechanism
摘要针对铁路噪声污染状况，根据提速列车运行噪声的特点及轮轨噪声产生的机理，研究了通过在钢轨轨腰镶嵌高阻尼材料从而降低轮轨噪声的技术。
