twisting vibration 中文意思是什麼
twisting vibration
解釋
扭曲振動-
The stiff floor structure has bigger displacement and smaller internal forces. under seismic forces, frame with eiastic fioor has bigger vibration period, and takes on complicated modes of vibration. due to the big vertical rotation, structure with elastic floor shows more prominently coupling vibration of bending rotating and twisting
如，彈性樓板的結構位移比剛性樓板結構的位移大，內力也是彈性樓板結構的大；在地震力作用下，考慮彈性樓板變形的空間框架振動周期比剛性樓板框架長，而且其振型表現得也比較復雜，由於豎向扭轉位移較大，彈性樓板結構表現出更明顯的彎扭耦聯振動。 -
Active control of bending - twisting couple vibration of plate using fuzzy control
壓電薄膜和模糊控制在板的彎曲扭曲振動控制中的應用 -
Abstract : the dynamic characteristics of unsymmetric ship structure with consideration of bending - bending - twisting coupled vibration and shear deformation are investigated, and the transfer matrices and a computing example are presented
