چکیده
|
In this article, transverse vibration of an euler-bernoulli beam carrying a series of traveling masses is analyzed. a semi-analytical approach based on eigenfunction expansion method is employed to achieve the dynamic response of the beam. the inertia of the traveling masses changes the fundamental period of the base beam. therefore, a comprehensive parametric survey is required to reveal the resonance velocity of the traversing inertial loads. in order to facilitate resonance detection for engineering practitioners, a new simplified formula is proposed to approximate the resonance velocity.
