Virtual Prototype Of Automobile Panel Optical Scanning Inspector

When inspecting the accuracy of automobile panel, as a result of the unreliable inspection results, having not the quality of tracking of the traditional inspection means, no digital integrated and so on, it is very difficult to meet the practical requirement. This paper mainly study related development technology and research results of a complete digital prototype of automobile panel optical scanning inspector (APOSI). The research applied advanced design idea and concept. It also lays the foundation for production line inspection and the complete digital integration of the automobile panel. So the research has an important engineering significance.The main contents of this paper are as follows:1) The working principle of the APOSI equipment. The inspection principle which is based on the alignment of the 3D point cloud is analyzed. Furthermore, it describes the equipment's function, parameters, structure and so on.2) The design of the APOSI equipment's main engine. Starting from the use of the environment and the analysis of the common Coordinate Measuring Machine, it is easily get the structural design of the equipment program. Then the key equipment's components are designed and the three-dimensional digital model is built in the UG environment.3) The equipment's simulation analysis which is based on ADAMS. The three-dimensional models are imported into the software called ADAMS. By adding constraints, attributes, sports and so on, the equipment's kinematics and dynamics simulation can be carried out.4) Finally, so as to make people have the intuitional feeling of the APOSI equipment, the geometry and behavioral model are constructed in the virtual environment, as well as the production web publishing.
