| 摘 要： | 为解决地震模拟振动台建模中的非线性问题,采用Matlab/Simulink中的Sim Hydraulics、Sim Mechanics模块对北京工业大学地震模拟振动台九子台阵进行了精细化建模与仿真,分析了伺服阀特性、台面质量及油源压力对系统频响特性的影响,给出了振动台建设中合理的台面质量范围,得出了试验中通常应该采用的理想油源压力.研究结果表明:伺服阀频率对振动台系统频响特性的影响较大而伺服阀的阻尼比对此几乎没有影响.

| Abstract: | In order to solve the nonlinear problems in the modeling of shaking table array system, refined modeling and simulation of shaking table 9 -sub array system of Beijing university of technology were carried out using Matlab/Simulink, the characteristics of servo valve, mesa quality and the effect of oil source pressure on the system frequency response characteristics were analyzed. The study shows that the servo valve frequency exerts great influence on the frequency response characteristics of shaking table system while servo valve damping ratio has little impact on the system frequency response characteristics. |
