Hot rolled steel plate for automobile body crossbeam is one of the most widely used steel plates for truck. This paper introduces the production status, consumption status, typical production enterprise and development trend of automobile body beam plate in China. The body beam is fixed on the foundation frame after the failure treatment, and is placed on the three coordinate platform with the characteristics of up-leveling, front girth, top cover, rear girth and side circumference as reference points, and the body crossbeam is adjusted in the body crossbeam coordinate system.
The "Digital shape Editor" module based on CATIA software can process the measurement point cloud quickly and conveniently, and draw out the contour feature line of the part prototype. The "fast surface reconstruction" module can set up and process the feature lines on the point cloud and fit the surfaces that meet certain requirements. The "creating surface design" module can be further processed on the established contour feature lines and basic surfaces. Creates higher quality surfaces. In order to complete the reverse design of the automobile body beam.
Key words: automobile body beam; reverse design; performance
