【优秀设计】基于UG的家电造型设计及动态仿真 关键词:三维造型设计;虚拟装配;运动仿真 Abstract Facing with the competitive market, manufacturers need to accelerate product development process, shorten the product design and development cycle. The continuous development of computer technology and computer graphics provides powerful tools for people, three-dimensional CAD/CAM/CAE integration software is widely used in manufacturing. Compared with the traditional assembly design, virtual assembly technology to meet the requirements of concurrent engineering, the design of their products can be equipped with timely detection of problems in product design, improve the assembly quality and assembly efficiency. This thesis based on UG product design platform for the fan completed the three-dimensional design. The shape structure of vertical electric fan is very complex, if using the traditional CAD drawing software to design will be very difficult, UG can easily solve this problem, the UG software has powerful functions of solid modeling, surface modeling, virtual assembly simulation, engineering drawing and others. This paper discussed the key link of fan that using reversal design progress from the physical to the mold in virtual design, as the part modeling, virtual assembly, dynamic simulation and the fan injection mold design. The paper also compared the advantages and differences between virtual for product design in the development of traditional design methods. Through the visual display assembly, interference analysis then to achieve accurate simulation campaign that produce real in high efficiency, high quality, short time, low cost environment.
