RISFree Vibration Analysis of Rods using Adomian Decomposition Method
. In this paper, this technique is applied to solve free longitudinal vibration of a uniform rod with various boundary conditions. At first, the frequency equation is obtained analytically and then ADM is used to calculate the natural frequencies and mode shapes...
Vibration Analysis of Long Cylindrical Shells Using Acoustical Excitation
the natural frequencies and mode shapes of a long circular cylindrical shell. A study was made to compare the predictions of the five analytical methods with experimental measurements. Interesting theoretical and experimental observations were observed...
Structural Damage Identification Based on Modal Data and Wavelet Analysis
A wavelet based damage identification method for beam like structures is presented in this paper. Mode shapes and modal strains of a reinforced concrete beam with three damage scenarios were analyzed through wavelet transform and the results were...
Free Vibration of Thin-Walled Cylindrical Shells
A method is presented for calculating the free vibrations of an isentropic thin-walled circular cylindrical shell with different boundary conditions. The method is based on Love’s theory of shells. An experimental study ...
Application of modal analysis to the watermelon through finite element modeling for use in ripeness assessment
detection of the vibration response of watermelons to predict ripeness. Finite element
modeling (FEM) was used to find the optimum location for excitation and response measurement and to
analyze the mode shapes. The model was considered based...
Investigation of nonlinear dynamic behavior of lattice structure wind turbines
Wind turbines are kinds of electricity generators, proliferating nowadays due to their consistency with
the environment. The rotation of the wind turbine blades duo to wind, burdens some frequencies on the wind ...
Free Vibration Analysis of Gabled Frame Considering Elastic Supports and Semi-Rigid Connections
Free vibration analysis of a gabled frame with elastic support and semi-rigid connections is performed by using a program in OpenSees software. Natural frequencies and mode shape details of frame are obtained for two states, which are semi...
