摘要
以摩天轮为例,采用大型有限元分析软件MSC.Nastran建立了仿真模型,对摩天轮承受满载、极限风载以及满载和极限风载共同作用这3种工况下的应力场和应变场进行了分析.研究结果表明,建立的摩天转轮有限元模型合理,模拟结果与实际情况相符,对指导和完善摩天轮的设计与优化过程具有重要的理论和实际意义.
Taking Ferris wheel as an example,numerical simulation model was established by using finite element software MSC.Nastran.Stress field and strain field under three work conditions as full load,limit wind load and interaction of full load and limit wind load are analyzed.The results show that the FEM model is reasonable and accords with actual condition,which has important theoretical and practical meaning to direct and improve the design and optimization of ferris wheel.
