结合结构动力学理论分析与地震模拟振动台的控制理论分析,给出东南大学4 m×6 m自行组装的单轴振动台的数学模型,并进行仿真分析,指出了系统在不同负载下的油柱共振及阻尼等参数;同时结合实际模型试验进行详细的试验分析.理论与试验的结果都证明了在这种组合模式的系统中,三参量控制能更加有效地改善系统动态特性,满足更多的试验要求.

Combining structural dynamics with the control theory of a shaking table, the dynamic model of a 4m×6m self-assembled shaking table was derived. Its oil column resonances and damping parameters were then obtained based on simulations. At the same time, a detalied test analysis was given according to actual model tests. Theoretical and ex-perimental results showed that a 3 -parameter control model was more effective to improve the dynamic characteristics of the system to meet additional test requirements.
