摘要
利用有限元分析法分析了双向门式启闭机在减轻钢结构自重的前提下,自身强度、刚度、稳定性能否满足要求的问题.通过对启闭机各种工况的详细分析,用ANSYS软件建立SHELL63弹性壳单元模型,对金属结构的连接、约束、载荷进行有效处理,对各种工况的应力、变形等进行严格的计算.由分析和计算结果知,启闭机金属结构的强度、刚度、稳定性均小于许用值,满足要求.
Using finite element method,this paper analyzes whether the bidirectional portal hoist can meet itself strength,stiffness and stability requirements on the premise of lightening the steel structure weight.By particularly analyzing various working conditions of the bidirectional portal hoist,the SHELL63 elastic shell element model was created by use of the software ANSYS,then the connection,restriction and load of the metal structure were processed effectively and the stress and deformation of various working conditions were calculated rigorously. The results proved that the strength,stiffness and stability of the hoist metal structure were all less than the admissible and met the requirements.
