Structural Synthesis for Prescribed Target Natural Frequencies and Mode Shapes [PDF]
Shock and Vibration, 2014 A new method for the synthesis of structures with prescribed target natural frequencies and mode shapes is presented. The introduction of a modal Rayleigh quotient approximation based on the target mode shapes is the means to propose a structural ...

Crack detection of a beam-like bridge using 3D mode shapes [PDF]
Vietnam Journal of Mechanics, 2014 In this paper, mode shapes of a 3D cracked beam with a rectangular cross section are analyzed for crack detection. The influence of coupling mechanism between horizontal and vertical bending vibrations due to the 3D crack model on the mode shapes is ...

SCALING OF OPERATIONAL MODE SHAPES USING SENSITIVITY ANALYSIS [PDF]
مجله مدل سازی در مهندسی, 2009 Recently, identification of dynamic properties of structures such as bridges, towers and building, which are not easy to excite, is possible by measuring only the output responses. Due to measuring only the responses when the structure is excited only by

Nonlinear Vibration and Mode Shapes of FG Cylindrical Shells
Latin American Journal of Solids and StructuresThe nonlinear vibration and normal mode shapes of FG cylindrical shells are investigated using an efficient analytical method. The equations of motion of the shell are based on the Donnell’s non-linear shallow-shell, and the material is assumed to be ...
