第一振型 meaning in English
first vibration mode
Examples
- Three kinds of control algorithms were used in this numerical simulation : the symbol control law , the first mode control law and the main mode control law
Kobori提出的符号控制律和在符号控制律的基础上引申出的振型控制律(包括第一振型控制律和主振型控制律)对半主动控制装置进行实时控制。 - The level first frequency variety regularity following the pre - stressing cable value is achieved through white noise sweep checking . the conclusion that model is in elastic work stage is achieved
对结构模型进行了振动台试验,采用白噪声对结构模型进行扫频分析,得出结构水平第一振型对应频率随拉索预应力值的变化规律。 - However , it is found that the second or the third order mode shape rather than the first order , are responsible for the seismic responses on free surface under many case in this paper
然而采用等效非线性化直接分析士层地震反应的实例计算结果表明在很多情况下，对场地地震反应起主要作用的不是第一振型而是第二、三阶振型。 - When the structural seismic responses of suspension - mass pendulums were analyzed with response spectrum method , the vibration modal numbers considered were to be structural first vibration modal and previous vibration modals of structural vibration as well
用反应谱法对悬吊结构进行地震反应分析时，所考虑的振型数应为结构的第一振型和相应于结构振动的前几个振型。 - And simulation analyses were carried out to examine the influence of the parameters of the controlled structures and the controllers on the control effectiveness of the system . the simulation results show that the different control laws ca n bring on the different control effectiveness
在隔震体系中，第一振型控制律和主振型控制律所产生的减振效果是相同的，因为隔震体系的第一振型就是主振型。
