Abstract

See full text

Multifunction noise suppression and crash structures are disclosed. In one aspect of the disclosure, the multifunction structure includes a body, inlet and outlet pipes, and a plurality of walls within the body that bound resonator cells and that are configured to suppress exhaust noise passing through the resonator cells from the inlet to the outlet pipes. The structure may be positioned between crash rails at the rear of the vehicle and between the engine and bumper. The walls may be generally aligned with, or near, the predicted impact direction and they may crumple in a controlled manner during an impact. In various embodiments the structure is 3D printed to enable construction of a wide diversity of geometric topologies and to minimize mass.
