โœฆ Synopsis

The complex mode superposition method for the dynamical analysis of a simply supported beam with two rotational viscous dampers attached at its end is presented. First, a numerical procedure for the evaluation of complex frequencies and modes of vibration has been worked out. Second, the appropriate orthogonality conditions have been established in order to decouple the equation of motion. The complex mode superposition method has then been used for the dynamic analysis in the time and frequency domains. Finally, some numerical applications, under impulsive and harmonic transverse accelerations of both ends, have been reported in order to illustrate the effects of the dampers on the response amplitude.

This paper contributes to the basic fundamental problem of vibration of elastic homogeneous isotropic beam with general boundary conditions traversed by moving loads. Closed-form solutions for the response of beams subjected to a single deterministic moving force are obtained. The moving force is as

An analytical model is proposed which consists of two Euler-Bernoulli beams joined by a torsional spring with linear and cubic stiffness. The method of harmonic balance is used to find an approximate solution for simply supported and clamped end conditions. Specifically, a one term harmonic balance
