Abstract The feasibility for absorbing the transverse vibration of a frame-beam induced by oscillating equipment using a vibrational absorber is studied by both theoretic and experimental approaches. Firstly, the modeling for the dynamic system composed by a piece of oscillating equipment and its supporting frame-beam is carried out, which turns to be an Euler-Bernoulli beam of distributed parameters supported elastically on its ends under the dynamic action of harmonic loading. And then a vibrational absorber is attached to the analytical model so as to theoretically analyze the feasibility for diminishing the transverse oscillation of a frame-beam induced by oscillating equipment. Finally, an experimental model is made to testify the possibility of the theoretic analysis. Both theoretic and experimental investigations show that it is feasible for diminishing the transverse vibration of a frame-beam due to oscillating equipment attached on the beam using a vibrational absorber.
