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.

Key words: 3D modeling design; simulation assembly; movement simulation
