Strengthening structure of a vehicle
A strengthening structure of a vehicle is provided that comprises a base having a first plurality of cutouts and relief members disposed across the base. Each relief member includes a cross section having a plurality of corners forming a plurality of inner and outer angles, a distal end, and an open proximal end in communication with one of the first plurality of cutouts.
1. A strengthening structure of a vehicle, comprising:
a base having a first plurality of cutouts and a second plurality of cutouts;
a plurality of relief members of variable height disposed across the base, each of the relief members having one of substantially uniform sides and substantially tapered sides and including:
at least a sixteen-cornered cross section having sides of variable lengths and thicknesses;
a distal end; and
an open proximal end in communication with a corresponding cutout of the first plurality of cutouts, wherein each of the second plurality of cutouts is free from communication with any of the relief members, and further wherein each of the second plurality of cutouts defines a cutout cross-section including at least three corners.
2. The strengthening structure of claim 1 , wherein the distal end is one of open, partially open, and closed.
3. The strengthening structure of claim 2 , wherein the distal end is closed and includes a raised central portion.
4. The strengthening structure of claim 1 , wherein the cross section includes one of sixteen corners, eighteen corners, twenty corners, twenty-two corners, twenty-four corners, twenty-six corners, and twenty-eight corners.
5. The strengthening structure of claim 1 , wherein the second plurality of cutouts are defined to alternate between the relief members.
6. A strengthening structure of a vehicle, comprising:
a base having a first plurality of cutouts;
a plurality of one of uniform relief members and tapered relief members of variable height disposed across the base and each including:
a cross section having about three corners to about forty corners and having a plurality of sides of variable lengths and thicknesses;
a distal end, wherein the distal end includes a raised central portion having a perimeter wall and a central cross section having at least three corners; and
an open proximal end in communication with a corresponding cutout.
7. The strengthening structure of claim 6 , wherein the distal end is open, partially open, or closed.
8. The strengthening structure of claim 7 , wherein the central cross section of the raised central portion is proportional to the cross section of the respective relief member.
9. The strengthening structure of claim 6 , wherein the base includes a second plurality of cutouts free from communication with any of the relief members.
10. The strengthening structure of claim 1 , wherein the relief members have at least sixteen-cornered cross sections shaped as a star.
11. The strengthening structure of claim 1 , wherein the relief members have at least sixteen-cornered cross sections shaped as a cross having angular ends.
