| Abstract: | The vertical shaking system of 3 -dimensional seismic simulating apparatus involves a dynamic shaking system and a gravity balance system. The gravity balance system with pressure close loop control serves as the loading system of dynamic shaking system. In this paper, the shaking system model with random disturbances is employed, and the dynamic characteristics of the multi-degree-of-freedom system with loading system are analysed and the simulating results are also presented. |
