Abstract:
A strengthening member for an automotive vehicle has a twelve-cornered cross section comprising sides and corners creating internal angles and external angles. The strengthening member also comprises one or more of trigger holes, convolutions, and flanges to stabilize the folding mode and prevent bending in response to an axially-applied crash force.
Abstract:
A strengthening member for an automotive vehicle comprises a twelve-cornered cross section including sides and corners creating internal angles and external angles. Each internal angle ranges from about 100° to about 110° and each external angle ranges from about 105° to about 130°.
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.

Abstract:
A strengthening member for an automotive vehicle comprises an eight-cornered cross section including sides and corners. The sides comprise four straight sides and four curved sides. A length of each straight side ranges from about 10 mm to about 200 mm and a length of each curved side is about 10 mm to about 200 mm.
Abstract:
Several different cross sections of beam having more than four sides are disclosed that may form a central portion of a beam having end portions that have four sides. The end portions of the beams may be received by frame rails. The central portion of the beam between the frame rails may be formed with more than four sides. The additional sides may be recessed beads or protruding ribs. Beams having arcuate recesses or arcuate ribs may be provided on the central portion of the beam. The end portions of the beams may extend outboard of the frame rails. The ribs or beads on the central portion of the beam may provide equivalent performance to four-sided beams having considerably thicker walls. Weight reduction is achieved because the central portion is made of a thinner material while retaining strength by forming beads or ribs in the central portion.
Abstract:
The present invention provides a method for manufacturing a metamaterial dielectric substrate, and a metamaterial dielectric substrate manufactured using the same. According to the metamaterial dielectric substrate and the manufacturing method thereof of the present invention, an arrangement rule of pin-shaped articles in a pin-shaped array may he predetermined during the manufacture, such that the formed metamaterial dielectric substrate has pinhole-shaped arrays arranged in a specific rule. Therefore, the metamaterial dielectric substrate may implement specific modulation functions on an electromagnetic wave such as electromagnetic wave divergence, convergence or deflection, thereby providing a more flexible design for function application of the metamaterial.
