The most characteristic work in shipbuilding industry is to bend thick steel plates. It is often said that plate bending technique is one of the most difficult ones. In order to solve those technological problems, a lot of investigations were conducted in the past 30 years in Japan. A series of investigations on universal press with multiple piston heads were studied, in order to automate plate bending process. The other approach was contributed by 4th. Subcommittee of the Systems Technology and Computer Application Committee. They proposed that such shipbuilding skills should systematically be analyzed to be applicable for researches on artificial intelligence and expert system. The aim of this paper is to develop a simulator for plate bending by line-heating. A Simplified non-linear elastic plate bending model is introduced instead of thermal elastic-plastic and large deformation analysis. Engineering work station is used in the main system and finite element analysis is carried out in numerical calculation. And the system supports good interface. So users can easily understand plate bending process intuitively and acquire know-how of it. The simulator is also useful as a training facility for technicians.
