Author: Jing Han, Jin Bao Ji, Yu Bin Ma

Abstract: In order to better understand dynamic characteristics of the structural testing system in Beijing University of Technology, ABAQUS software was adopted to build a mechanical finite element model of the system. Static analysis under real loading and modal analysis was conducted and the 4 natural frequencies and modes of the model were obtained. The influence on natural vibration characteristics by rack stiffening plates of the structural testing machine was studied. The studies of this paper may be useful for designing and functional improvement of structural testing machines.
