Air blast wave protection

摘要

A method of designing a wearable air blast wave energy protection device includes computer modeling at least two candidate reflective materials for a first human-protective and primarily reflective response to a specified incident air blast wave energy. The method includes selecting a layer of a first material from the at least two candidate reflective materials based at least partially on the computer modeling of the at least two candidate reflective materials. The method includes computer modeling at least two candidate attenuative materials for a second human-protective and primarily attenuative response to the specified incident air blast wave energy transmitted through the selected layer of the first material. The method includes selecting a layer of a second material from at least two candidate attenuative materials and electronically maintaining informational data corresponding to the selected layer of the first material and the selected layer of the second material.

1. A method of designing a wearable air blast wave energy protection device, the method comprising:
(a) computer modeling at least two candidate reflective materials for a first human-protective and primarily reflective response to a specified incident air blast wave energy, the computer modeling of the at least two candidate reflective materials at least partially based on respective acoustic impedances of the at least two candidate reflective materials to the specified incident air blast wave energy, the respective acoustic impedances of the at least two candidate reflective materials each substantially mismatched to an acoustic impedance of air; (b) selecting a layer of a first material from the at least two candidate reflective materials, the selecting based at least partially on the computer modeling of the at least two candidate reflective materials; (c) computer modeling at least two candidate attenuative materials for a second human-protective and primarily attenuative response to the specified incident air blast wave energy transmitted through the selected layer of the first material, the computer modeling of the at least two attenuative materials at least partially based on respective inelastic responses of the two candidate attenuative materials to the specified incident air blast wave energy transmitted through the selected layer of the first material; (d) selecting a layer of a second material from at least two candidate attenuative materials, the selecting based at least partially on the computer modeling of at least two candidate attenuative materials; and (e) electronically maintaining informational data corresponding to the selected layer of the first material and the selected layer of the second material.
