吊运危险物品起重机械抗震性能研究

Assumption of Seismic Behavior of the Lifting Ma chinery for Lifting Hazardous Goods

本文参照相应的抗震研究规范和现有抗震研究方法,提出针对吊运危险物品起重机械抗震性能研究的设想。本文提出利用ANSYS谱分析技术将模态分析和地震反应谱进行耦合,并对研究过程的一些关键问题进行了阐述。通过研究起重设备在地震过程中动态响应,可以为起重机械相应的抗震设计内容提供补充,促使相关标准进一步完善,并通过分析结果,为震后有关起重设备的检测和修复提供一定的指导。

This thesis presents the assumption of seismic he havior of the lifting machinery forlifting hazardous goods, referrin g to existing norms and methods of seismic research. In this thesis, the modal analysis and seismic response spectrum are coupled by using ANSYS spectrum analysis technique, meanwhile, some key issues of the research are also discussed. Through studying on dynamic response of the lifting machinery during earthquake, th e assumption provides additional content for seismic design, promp ts further improvement for relevant standards, and offers guidance f or detection and repair of lifting equipments after earthquake by au alyzing the results.
