| 摘 要： | 车辆运行过程中引起的竖向地面微幅振动是影响高科技厂房精密仪器正常运行的重要因素。本文采用隔振与主动控制相结合的混合控制系统，以高科技厂房及精密仪器工作平台的有限元动力方程为基础，采用子优化控制方法建立了高科技厂房及精密仪器工作平台的分析模型，探讨了车辆运行所引起的高科技厂房精密仪器工作平台竖向微幅振动的混合控制分析方法。一座典型的三层高科技厂房的算例分析表明，采用混合控制方法能够有效地减小高科技厂房精密仪器工作平台的竖向微幅振动。 |

| Abstract: | This paper explores the possibility of using hybrid control platform to mitigate the vertical microvibration of a batch of sensitive equipments installed in high technology building subjected to nearby road vehicle-induced ground motion. Two-dimensional dynamic equation of motion of a typical three-story high technology building is established by using finite element method. Hybrid control system composed of passive mounts and active hydraulic actuators is then constructed with sub-optimal control algorithm based on the finite element model of the building structure. The simulation results show that the performance of hybrid control platform is superior to that of passive control platform because of the higher performance and robustness. |
| Keywords: | high technology building platform vertical ground motion hybrid control vehicle |
