The transient dynamics of multiple accelerating/decelerating masses traveling on an initially curved beam

Result of present study shows that the initial curvature of a beam can result significant effects to the dynamics of the system even if the initial imperfection of the beam is small. The magnification of the amplitude of response of the system due to the initial deviation of beam depends on the initial speed of mass, the applied forward/retard force on the mass, and the friction between the mass and the beam.
