Vibration Control of Traveling Crane with a Novel Tuned Mass Damper

摘要

Traveling crane is an important equipment of stereoscopic warehouse. The traveling crane is desired high efficiency for storing and retrieving by more and more consumer of warehouse. Thus, more higher velocity and acceleration of the traveling crane are all needed. However, they are restrained by many factors. The swing of mast is one of the most important factors. So, it is necessary to control the swing. In this paper, a scheme is presented to suppress the swing of the mast by TMD (tuned mass damper) but no extra mass is attached to the main structure. In this scheme, the upper beam is used as attached mass. So, the only necessary modify is that the juncture between the mast and the upper beam according to the desired dynamic parameter of TMD. The main principle of the scheme is introduced firstly in the paper. Then, the natural frequency and mode shape is calculated by means of FEM (finite element method) based on software ANSYS. After that, the dynamic response of the mast is simulated by means of the software SIMULINK of MATLAB. The result of measurement is introduced at last. The result shows that the scheme is feasible.
