Abstract:

Analyzing the nonlinear vibration of beams is one of the important issues in structural engineering. According to this, an impressive analytical method which is called Modified Iteration Perturbation Method (MIPM) is used to obtain the behavior and frequency of a cantilever beam with geometric nonlinear. This new method is combined by the Mickens and Iteration methods. Moreover, this method don’t require small parameter in the equation which is difficult to be found for nonlinear oscillation. The accuracy of the solution that is obtained by using of MIPM has been shown graphically and compared with exact solution. Comparison shows that good adaptation is obtained and MIPM is a powerful method for solving the vibrational behavior of structures analytically.

An Overview of Disarray in Nonlinear Vibration Analysis of Cantilever Beam with Damped Dynamic Vibration Absorber with Adjustable Stiffness with Nonlinear Parameters

Vibration is omnipotent, universal and multifaceted phenomena. It is an interdisciplinary field where physicist, mathematician and engineer interact in a closed loop. Vibration absorption is a method of adding a tuned springmass absorber to a system to create anti-resonance at a resonance of the original system. Most real-world phenomena exhibit nonlinear behavior. In these paper overviews of v...

Nonlinear Vibration Analysis of the Beam Carrying a Moving Mass Using Modified Homotopy

In the present study, the analysis of nonlinear vibration for a simply-supported flexible beam with a constant velocity carrying a moving mass is studied. The amplitude of vibration assumed high and its deformation rate is assumed slow. Due to the high amplitude of vibrations, stretching is created in mid-plane, resulting in, the nonlinear strain-displacement relations is obtained, Thus, Nonlin...
