Energy absorber for high performance blast barrier system

摘要

The present invention provides an energy absorber for a blast barrier system comprising a substantially tubular member extending longitudinally along an axis from a first end portion to a second end portion, each of the first end portion and the second end portion having a substantially similar geometric, profile, wherein the energy absorber collapses under a predetermined load when compressed by a residual blast force. The energy absorber of the present invention may help minimize damage to people and structures by further dissipating force from a blast in a blast barrier system.

主权项

1. A blast barrier system comprising:
a blast panel; a beam; an energy absorber comprising a substantially tubular member extending longitudinally along an axis from a first end portion to a second end portion, each of the first end portion and the second end portion having a substantially similar geometric profile, and the energy absorber having a first side, and a second side located on a substantially opposite side of the absorber from the first side, and each of the first side and the second side are parallel to the axis from the first end portion to the second end portion; wherein the beam is attached to the first side of the energy absorber, and is substantially parallel to the axis from the first end portion to the second end portion of the energy absorber, wherein the blast panel is attached to the second side of the energy absorber, wherein the blast panel flexes when compressed by a blast force, and wherein the energy absorber collapses under a predetermined load when compressed by a residual blast force.
