✦ Synopsis

Vibrational behavior of elastic homogeneous isotropic beams with general boundary conditions due to a moving harmonic force is analyzed. The analysis duly considers beams with four di!erent boundary conditions; these include pinned}pinned, "xed}"xed, pinned}"xed, and "xed}free. The response of beams are obtained in closed forms and compared for three types of the force motion: accelerated, decelerated, and uniform motion. The e!ects of the moving speed and the frequency of the moving force on the dynamic behavior of beams are studied in detail.

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

The method of modal analysis is presented to investigate the random vibration of a multi-span Timoshenko beam due to a load moving at a constant velocity. The load is considered to be a stationary process with a constant mean value and a variance. The effects of both velocity and statistical charact
