尾部弯曲振动形式 - As a special form of vibration , flutter is a major feature closed with the run environment and safety of aircraft , which is an important project of human - machine - environment engineering
作为一种特殊的振动形式，颤振与飞行器的运行环境和安全性密切相关，是人机与环境学科的一个重要研究课题。 - The result indicates : when the transverse crack was contained in the crankshaft , the crankshaft ' s natural frequency reduced obviously , but does not change the vibration form of every type
结果表明，曲轴在含有横向裂纹后，其固有频率有很明显的降低，但是不改变各阶振型的振动形式。因此，固有频率的降低可以作为曲轴中含有横向裂纹的标志。 - But in a long period of time , condition monitoring of the machinery and fault diagnosis are based on the analysis of the signal coming from single channel the vibration of the rotor is a dimensional conception
但是长期以来，机械状态监测和故障诊断大都以单通道信号分析为基础。转子的振动形式是个空间的概念，单通道信号只是转子在传感器方向上振动的反映，所能提供的转子振动信息并不十分准确、完整。 - Chapter three discusses the vibration forms of the surface dynamic rotating drilling downhole drilling string , analyzes the damage of low frequency ancf fongif ucfi ' na / vibration to downhole drilling string , and set up a set of math models of the longitudinal and torsional vibration
第三章分析探讨了地面动力旋转钻井井下钻柱的的振动形式，并提出分析了低频纵振现象对井下钻柱的损害，以及建立了纵向、扭转振动的数学模型。
