A method simulates a vehicle crash on a fuel delivery module (11) of a vehicle that has a flange (10) coupled to a fuel tank, a fuel pump (12), a reservoir (18) housing the fuel pump, and strut rods (14). Each strut rod has an end coupled to the reservoir or fuel pump and another end coupled to the flange at an interface. The method models a fuel tank as a rigid or elastic shell. A solid model of the fuel delivery module is created and meshed to create a finite element model. Fluid in the fuel tank is modeled with Lagrangian or arbitrary Lagrangian Eulerian finite elements, or smoothed particle hydrodynamics particles. Solid fluid interactions are added to the meshed solid model. A vehicle crash simulation is run on the solid model together with the fluid interactions to determine the effect of the fluid interactions. |
