A method is provided for simulating a vehicle crash on a fuel delivery module of a vehicle. The fuel delivery module () has a flange () constructed and arranged to be coupled to a fuel tank, a fuel pump () for delivering fuel from the tank and through the flange, a reservoir () housing the fuel pump, and strut rods (). 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 associated with the fuel delivery module as a rigid or elastic shell. A solid model of the fuel delivery module is created. The solid model is 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 on the interface of each strut rod with the flange and to determine any effect on the flange.

Fluid solid interaction included in impact simulation of fuel delivery module

A wire harness assembly and flange combination of a mechanical returnless fuel system includes a wire harness assembly () having at least two terminals (). Each terminal is joined with at least one wire () via an electrical connection (). Diode structure () is electrically connected between the at least two terminals. A body () of plastic material encapsulates at least the electrical connection. A flange () is molded from plastic material and defines an inside region () and an outside region (). The terminals are accessible from the outside region of the flange, with ends of the wires being accessible from the inside region of the flange. The plastic material of the flange encapsulates at least a portion of body, the diode structure, and at least a portion of the terminals.
