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.
