浮放设备的隔震技术研究
|
摘要
在地震过程中,由于贵重浮放仪器设备绝大部分未采取防震措施,会发生滑移、倾覆、或碰撞,不仅使贵重浮放仪器设备遭到损坏或导致仪器设备的精度下降或性能下降,有时还会引起所控的系统运行停止或发生误动作,进而造成更大的二次损失。本文研究的主要内容如下:
1、针对一个框架结构实例,用Ansys软件建立非隔震结构和隔震结构有限元分析模型,对两种结构体系在地震作用下的地震反应进行分析;由此来分析基础隔震结构相对于非隔震结构在地震的隔震效果,并且探讨了基础隔震结构对浮放物体的防护效果。
2、进行浮放物体水平滑移理论的分析,建立浮放设备的有限元模型,进行物体与楼板面的接触分析,初步讨论物体在地震作用下滑移运动的特点。
3、总结现有的浮放设备防震设计方案,在理论分析的基础上提出防震措施,来提高贵重浮放仪器设备的抗震对策水平。
In the Process of the earthquake, as the majority of valuable equipment has not taken seismic measures to avoid slipping, overturning, or collision, the equipment will be damaged or the accuracy of performance will decreased . Sometimes the control system will stop or malfunction,which will result in greater loss.
The main contents of this paper is as follows:
1.Take the structure of a framework as a example, using Ansys software to establish finite element analysis model of a non-isolated structure and isolated structure . Analyze the dynamic response of the two structural system in the level of earthquake. Discuss the protective effect for the equipment of base-isolated structures.
2.Put the theoretical analysis of the level slipping theory of floating objects . Establish finite element model of floating device, analysis block contact with the floor surface, preliminary discuss the characteristic of block-seismic slip.
3.Summary of the existing earthquake design of the floating objects. Based on the theoretical analysis, earthquake measures are proposed to increase the level of seismic response of floating equipment.
