摘要
本文研究的是格架吊车的动力效应评价问题。本研究涉及的动力作用有:风、移动荷载和地震,假定为时变作用。研究从大型起重机的设计开始,采用这些结构的经典标准(UNI EN 13001系列)。通过分析方法进行详细阐述,然后进行实体模型构建和有限元分析(Solidworks®和Ansys®软件)。下一步是定义上述作用在这些结构上的载荷。将风的作用模型与静力法进行了比较。载荷位移对起重机结构产生高强度作用;为了更好地理解这些影响,模拟了几个负载曲线。最后考虑的作用是地震现象,在设计这类结构时通常不采用地震现象。
Dynamic effects on the lattice boom crane due to the wind, moving load and earthquake events
The present research concerns the evaluation of the dynamic effect on lattice boom cranes. The dynamic actions involved in this research are: wind, moving load and earthquake, assumed as time-varying actions. The research starts with the design of a large crane by adopting classical standards for these structures (UNI EN 13001 series). The elaborations were performed by analytical methods followed by solid model building and finite element analysis (Solidworks® and Ansys® software). The next step was to define the aforementioned loads acting on these structures. The wind action model was compared with the static approach. Payload displacement induces high-intensity actions on the crane structure; to better understand these effects, several load curves were simulated. The last action considered is the earthquake phenomenon, which is not usually adopted to design this type of structure.
