Chinese translation for "第二振型"

second vibration mode

Example Sentences:

	1.	This thesis will present a new simple method to calculate the seismic response of the framed structures . this method calculates the effect of the first and second modal vibration . the first modal shear force of every floor distributes according to the shape which is close to the first modal shape 本论文提出了一种新的计算框架结构地震作用效应的简化方法，考虑前两个振型的作用，对于第一振型的各层剪力，按照近似于基本振型的形状分布，第二振型各层剪力引用廖河山提出的方法计算，然后用将两个振型的剪力“平方和开平方”的方法，计算得到各层剪力(总效应) 。
	2.	It is shown by structural seismic response of four wavelets that littlewood - paley wavelet is not suitable for structural seismic response , because structural response is too small , meyer wavelet is a better wavelet for structural seismic response , for it ' s structural response is agreement with the finite element method , and also harmonic wavelet , structural response under earthquake is a little bigger than finite element method , structural response under odd exponent wavelet is also bigger than finite element method , this method is very simple by wavelet transform , wavelet transform method is different from old methods , one is with which not only knows the effects of earthquake wave detail frequency - band on structural response , but also considers earthquake wave ' s non - stationary of frequency and time - domain value , another is the second mode shape and higher mode shape response that do n ' t attenuate so fast 通过对这四种小波的结构地震反应分析研究说明： littlewood ? paley小波不适合于用来作结构地震反应分析，因为在littlewood ? paley小波下的结构地震反应太小，不符合实际情况；用meyer小波作结构地震反应分析比较合适，和有限元法的结果比较接近；也可以用谐波小波来作结构地震反应分析，只是在谐波小波下的结果略为偏大；单边指数小波下的结构地震反应分析比有限元法稍大一点，它通过小波变换大大简化了结构地震反应分析。用小波变换方法来进行结构地震反应分析和以往方法不同的是：它不仅可以知道地震波的具体频率段对结构反应的影响，而且同时考虑了地震波的幅值非平稳性以及频率非平稳性；另外与以前方法得到的结果有差异的是，第二振型及以后的高一点的振型的反应没有以前的方法衰减得快。
