利用实体建模软件UG建立了卷扬机卷筒的虚拟样机,应用UG NX其“高级仿真”模块,建立卷筒的有限元模型,通过解算器NX NASTRAN对有限元模型进行分析求解,得到卷筒在受力作用下应变和应力分布情况,再根据设计要求对零件参数进行优化,使卷筒的结构既满足设计要求,达到体积小和成本低的要求.%The virtual prototype of the Hoist drum is built with 3D solid modeling software UG. UG NX 'advanced simulation' module is used to establish the finite element model of the hoist drum and by NX NASTRAN solver the finite element analysis model of hoist drum is solved for its rated load and the displacement and stress distribution of deformation are obtained. Then the part design parameters are optimized, so that the part size is reduced and its cost is lowered.
