Abstract: To deal with data security and resource sharing in collaborative design of car security between carmaker and suppliers who were on the remote, heterogeneous platform in automobile industry, a car crashworthiness collaborative design system was proposed based on grid technology. And a grid application middleware oriented to collaborative analysis in Computer Aided Engineering (CAE) was also proposed. This system was conforming to the Open Grid Services Architecture (OGSA) framework, and Web services. VEGA, a grid middleware with proprietary intellectual property rights, provided basic grid service. This middleware provided finite element model assembly service, computation monitoring service and results processing service for car crashworthiness collaborative design. Based on Web service technology, it also realized integration with grid system. Finally, a test bed was set up based on Local Area Network (LAN). This proposed system was applied in a collaborative design of a carmaker and a door supplier, and a satisfactory result was obtained.
