查询词典 shock wave

On the basis of dual feature identification method, combined with small wave analysis, it effectively extracts failure features, analyzes the stability power failure vibration signal feature on the general Fourier atlas, analyzes the shock power failure vibration signal feature on the resonance modulating Fourier atlas, using small wave to analyze the shock failure vibration signal feature.

是一种在"双特征判别法"的基础上，结合小波分析，有效提取故障特征，进行诊断的"三特征判别法"，所述的故障信号"三特征判别法"就是：在常规傅立叶谱图上分析平稳功率故障振动信号特征，在共振解调傅立叶谱图上分析冲击功率故障振动信号特征，利用小波分析冲击故障振动信号特征。

The process of shock acted on a vibration and shock isolation system with double-stiffness was divided into two steps. In the shock action phase of a half sine wave, the response was calculated by using a double DOF model. In the free vibration phase, the response was calculated by adopting a single DOF system, the initial displacement and velocity of single DOF adopt the final value of the first phase.

将环境对双模量隔冲减振器的冲击分为两个阶段，在半正弦波冲击作用阶段采用双自由度模型进行响应计算，并以终了时刻的位移和速度作为自由振动阶段的初始条件，对自由振动阶段的单自由度模型进行响应计算。
