常规工况下塔机整体钢结构应力分析及其振动特性研究
Research of stress and vibration of the whole steel structure for tower crane under normal loading
摘要
Abstract
The tower crane is an important construction equipment in the building construction,the safety performance evaluation of its metal structure in use directly affects the safety of use,and in order to avoid resonance phenomenon of the tower crane's steel structure in operational process,it is necessary to research the vibration characteristics of the tower crane.In this paper,taking a tower crane as the research object,according to the typical working conditions,the finite element model,stress analysis and the model analysis of the tower crane are completed,and the stress state of the tower crane under normal conditions,the first six order natural frequency and vibration mode are gotten,then the key detection position of the tower crane in the work process is obtained,which provides the theoretical support for the optimization design of the tower crane.The results have important significance for the optimization design and safe use of the tower crane.关键词
