Study On Sizing Press Energetic Analyze And Structure Optimization Design

Under the market competition condition, new product development technology is becoming more and more important. The market occupancy and corporation survival all rely on the development of new product. Mordern corporation need the ability of rapidly and efficiently development of new product. For traditional product like motocycle, unpredictable and changing of market requirement bring difficulty to market location of new product, potential customer requirement inquisition, transformation of customers' requirenent, formation , selection and valuation of new product concept and function configuration of new product.The digital design and management of 50cc scooter ZIP of ZongShen company development were presented in this paper. Zongshen company is one big privately owned company which produce motorcycle. For the satisfaction of market requirement of 50cc scooter, Zongshen corporated with Biyaqiao engine company Italy and developed a new product. The market location of new scooter, customers' potential requirement inspection, customer's requirement transformation, the formation, selection and valuation of new scooter concept, configuration and general layout of new scooter, engineering design, human being design, drawing of development plan are all main content of concept design.Taking the development of Zongshen 50cc scooter as an example, the new product development technology was summarized. Firstly, the scooter's fasion and scheme were selected based on QFD in concept design phase. Then the design of sturcture and general layout of scooter were researched. The structure of scooter was optimized by combination of virtual prototype and practical test. After the reverse engineering of clay model produced according to selected fasion, the digital model of new scooter was achieved. Finally, the rationality of structure and layout, and interference were detected through digital prototype and structure prototype.
