  • Publication number: 20230365084
    Abstract: A structure for a vehicle includes a body and an energy absorber assembly. The body extends in a transverse direction of the vehicle and is configured to be secured to a main body structure of the vehicle. The energy absorber assembly extends from the body. The energy absorber assembly also includes arcuate absorber elements configured to deform laterally upon impact in a longitudinal direction of the vehicle. When a vertical force is applied to the structure, the body is configured to inhibit deflection of the structure in a vertical direction.

  • Publication number: 20170106915
    Abstract: A crush can to an automotive vehicle has a twelve-cornered cross section comprising sides and corners creating internal angles and external angles. A geometry of the cross section varies between a front section and a rear section of the crush can. The geometry of the cross section is optimized using a plurality of control parameters including a lateral width, a vertical width, a taper ratio, a front scaling factor, and a rear scaling factor.

  • Patent number: 9533710
    Abstract: A method for optimizing a twelve-cornered strengthening member comprises: modeling a vehicle assembly including a strengthening member having a twelve-cornered cross section; parameterizing a geometry of the strengthening member with a plurality of control parameters; defining a design of experiment using the plurality of control parameters; modeling a vehicle using the vehicle assembly; simulating a frontal impact event with the vehicle; generating a response surface based on the frontal impact event; and determining a set of optimized control parameters for the strengthening member based on the response surface.

  • Patent number: 8109535
    Abstract: According to one embodiment, the invention provides for a light truck including a frame with opposing longitudinal frame rails running along each side of the vehicle. The frame rails include at least a leading portion with vertical placement lowered and selected to substantially align with a passenger car energy management structure. In this embodiment, the vertical placement of the leading portion of the light truck frame rails is selected to direct impact energy to a passenger car longitudinal energy management structure, improving vehicle-to-vehicle compatibility in the event of a front longitudinal impact with a passenger car. The present invention also provides embodiments which increase the impact energy absorption capacity of a light truck by providing geometric softening of the frame rails and material softening of the frame rails.
