The air-conditioning equipment and other structures attached to railway rolling stock are plate objects joined by a spot or an intermittent welding. The finite element (FE) modeling of such plate objects is very time-consuming due to the large number of spot and intermittent welds that must be modeled. We developed automatic weld modeling technology, with the aim of reducing the procedures for FE modeling. Applied to a test cover model, the technology reduced the modeling time to 1/3. And FE stress analysis showed that the result accorded to an experimental data within an error range of 11%.
