Abstract
In order to correspond flexibly to specification changes and light weighting and downsizing of the vehicle body, it is required to clarify and optimize the interface characteristics of the boundary portion and the functions of the module and components involved in the overall performance, in the early design stage. To solve the problems described above, we add the self-contact function within parts and the contact function with parts outside to the three-dimensional nonlinear finite element program consisting of non-linear spring elements and beam elements which has been developed intended for use in conceptual design stage, and carry out the verification analysis.
