The automobile elevator sedan frame is composed of the main sedan and the vice-sedan frame. Main sedan with vice-sedan by respective putting up the uppert beam, the straight beam, the under beam to be composed separately, connection mode by bold fastening primarily. Using Solidwoks software to design the main components of a sedan modeling and the completion of the necessary mechanical calculation.
To solve the problem it is difficult to accurately measure the curve surface, the forming mechanism of reverse engineering modeling approach is studied. Using the non-contact measurement of laser scanner, the point cloud data of the compression molding bodies is obtained, and it is introduced into the three-dimensional software CATIA to generate 3D model according to the molding processing point cloud and compression molding mechanism. In the last to generate the complete engineering drawings. Comparing the traditional design method, the method is mainly used for 3D parts reconstruction and design in surface shape is difficult to accurately expressed or unknown component shape design methods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
