Vibration Analysis of Axially Moving Beam with Different Load and Stretching Laws
The vibration equation of the axially moving cantilever beam under the effect of a moving mass is derived based on the Euler-Bemoulli model. The Galerkin method is applied to disperse the governing partial differential equation. Then the method of Newmark-β is chosen to solve the resulting ordinary differential equations. The effects of different weight and velocities of the moving mass and the various beam stretching speeds on the dynamic property of the cantilever beam are investigated. The results show that the moving mass and the stretching movement induce the time-varying property of the beam and have notable effects on the beam dynamic responses. The heavier of the moving mass, the larger of the displacement response of the beam can be induced. However, the effect of velocities of the beam and moving mass should be considered synthetically.
