The experimental results show that the proposed controller with the piezoelectric actuator can effectively reduce the vibration of the cantilever beam with an eccentric tip mass. The piezoelectric sensor can measure vibration responses with high-accuracy. Therefore, this new model gives a broad range ...
The representation of residual force vector was derived in detail on the basis of free vibration differential equation. A cantilever beam of rectangular cross section was studied by numerical simulation and experiment. The above mentioned method was applied to the experiment and its efficiency was demo...
A strip-shaped specimen rigidly bolted to the force sensor forms a clamped–free cantilever beam. Placed in a furnace, it is subjected to free-bending vibrations followed by a fast Fourier transform for identifying the resonant frequency, whereby Young's modulus is calculated from the Euler–...
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 nonlinea...
This work aims at developing a new dynamic model for the vibration control using the finite element analysis using comparing the effects of different controllers on system performance. The finite element method (FEM) is used to derive the flexible beam model. Frequency analysis (modal and harmonic...
