Synchronization Engineering Research Of Body Shape And Body Structure Design

In recent years, the world automobile environment are quietly changing: the production cycle is shortening, product upgrading faster; customer consumer value consumption and structure have been changed, customer's demand is not only diversified, personality, but also on product features, quality and reliability requirements, thereby increasing the auto market competition. Faced with fierce market competition, national car makers are seriously researching how can bring high-quality, low-cost products to the rapidly changing market in the shortest possible time in order to meet customer needs and market competition to win the victory. In China, with the large number of computer applications in the car, the condition of synchronization works in the automotive design is gradually mature.In the body design stage, to carry out structural design analysis, get the structure which is lightweight, safe and avoid interfering campaign, in advance of the foreseeable conflicts and reasonable solution, while effective guarantee of the body structure design process requirements. Synchronize engineering design can improve efficiency, avoid the conflict between the need of structural design and body design, or have to modify the initial shape in engineering design phase.Synchronize engineering make enterprises able to see the entire product life cycle at the design stage, it is a design mode that based on the entire life cycle of products, has high predictability and preventive. It should be noted that, some people simply think that synchronize engineering production is equivalent to the parallel or parallel work and the synchronize engineering is carrying out design process and production activities at the same time or staggered time. This view is wrong. Synchronize engineering's biggest characteristic is stressing that all the design work should be completed before carrying production.In the body design stage, for intensity of body coverage, coverage stamping, welding technology, engineers should involve in design at early stage in order to avoid the rework in late at the conceptual design stage.This paper describes the analysis for the main section of the body structure design, the appearance of tolerance design, sheet metal forming, welding technology, switch component motion interference analysis in modeling stage. The discussion of research method for the synchronize engineering of automobile body and structural design could effectively solve series of conflicts such as lightweight design, assembly structure, motion interference in the physical design or evaluation stage.Through the synchronization engineering research for body shape and body structure design, we can be expected to know the actual results of the design, give the content of evaluate and indicators of evaluation, solve the conflict of body design and structure design, shorten the product development cycle and prototype periodic cycle, have a certain guide for China's own body design development.
