Fiber composite intensive virtual urban vehicle structure

A design approach is presented applying an innovative method for supporting the development of a complete future urban vehicle structure made of fiber composite material down to component level. Based on a vehicle concept for urban transport, various FEM optimizations are carried out in order to construct appropriately to most-ideal loading paths and the use of fiber reinforced polymers (FRP). The optimization routines (including topology, free-size and size) are applied to volumes, surfaces and combinations thereof under static loads, including isotropic and anisotropic material models. As an example the optimization results of the vehicle floor and tunnel structure are presented
