摘要
UG提供了一种产品工程解决方案,可对产品设计与加工全过程实现数字化造型与验证。采用UG软件完成电动自行车主要机械零部件三维设计与虚拟装配,其中也利用其Senario?for?FEA模块对电动车关键零部件展开有限元分析;虚拟装配可实现零件静态干涉检查、装配路径规划等,有限元分析也促进了零件的进一步优化。最后,文中简述UG的运动学分析方法,其操作简单,可视化。通过运动件各关键点的位移、速度、加速度等变化规律曲线,从而轻松获知其运动特性。
UG software provides a kind of solution in Product Engineering,which may achieve digital modeling and verification for product design and machining process.3D design and virtual assembly for key mechanical parts of e-bike（electric bicycle）are accomplished by using UG.Meanwhile Finite-element analysis for the key parts has been done with UG/FEA as well.With the virtual assembly,static interference checking,layout planning for assembly is achieved.And the further optimization for the parts is realized by finite element analysis.As a result,the UG kinematics analysis method is expounded,which operation is easy and visualized.From the variational rule curve of speed,acceleration and displacement for key points of the moving parts,the characteristics of kinematics is obtained easily.
