摘　　要：我国自行设计的三向大型地震模拟振动台的竖向激振系统采用动态激振系统与静力平衡系统一体的结构方案．静力平衡系统采用压力闭环控制构成了动态激振缸的加载系统．本文以带有随机干扰的激振系统模型为基础，对这种具有加载系统的多自由度系统进行了分析和仿真研究．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.
