摘要
根据微振动控制的要求,采用有限元软件ETABS建立了某高层建筑的整体分析模型,模拟在仿真风和动力设备作用下精密仪器所在位置的楼板振动响应;采用有限元软件ANSYS建立了精密仪器隔振台座的子模型,将整体模型的振动输出作为子模型的振动输入,从时域和频域两个方面进行了精密仪器的微振动控制分析,为工程的具体实施提供了理论和计算依据。
According to the requirement of micro-vibration control,the integrated finite element model of a high-rise building is established with respect to software ETABS so as to simulate the vibration responses of the slab subjected to the simulated wind load and the dynamic facility action where the precise instruments are fixed.By use of the software ANSYS,the sub-model of the vibration isolated plat-form of the precise instruments is established,in which vibration inputs are the whole model's outputs and the analytical data and theoretic foundations are obtained for the control of the instruments vibration both in the time domain and frequency domain.
