低频振动 meaning in English
low frequency vibration
low-frequency vibration
Examples
- By observing the frequencies of each shaft of the compressor set , sorting out the feature frequencies which may stimulate probable mal - functions of low frequency vibration , then examining the characteristics of signals ' spectrum charts and brushing away any other causes , it can be confirmed that the lower frequency is the clap - frequency of that set
考察压缩机组各转轴的频率后，分析可能激发低频振动故障的各特征频率，观察有关测点频谱图的特点，逐一排除其他原因，确定该低频项为压缩机的拍频。 - A lot of engineering applications are carried out using our proposed method in this paper , such as thermal deformation measurement of a car lamp , analysis of the super low frequency harmonic vibration of a piezoelectric ceramic , dynamic mechanical behavior analysis of the ballistite material and so on
在前面所提出的理论基础之上，本文对该方法在实际工程中的应用做出了大量的工作。本文利用时间序列法实现了汽车前灯配光镜的热变形检测、压电陶瓷片的超低频振动分析以及火箭固体燃料的动态力学特性研究。
