On the vibration of a thin rectangular plate carrying a moving oscillator

A great number of studies on the vibration of plates subjected to moving loadsare available, which are gained by moving force and moving mass modeling frameworks.as a result, evaluating the reliability of the approximate simulation of a moving oscillatorproblem through moving force/mass would be of interest to engineering applications.therefore, in this article, transverse vibration of a thin rectangular plate under a travelingmass-spring-damper system is revealed using the eigenfunction expansion method. bothmoving force and moving mass modeling approaches are compared with the movingoscillator and various plate xity cases, and load trajectories are involved to presentbenchmark solutions. the spring stiness range, in which the plate response agrees closelywith the corresponding moving force/mass analysis, is recommended. the results elucidatethat the moving mass can be considerably unrealistic in predicting the contact force ofan undamped oscillator. moreover, errors in the orbiting force/mass simplication ofthe orbiting oscillator in predicting the resonant conditions of the plate vibration are notnegligible.
