Benefits of technology

[0007] By using the above anomalous behaviors of total transmission which are propagating features of an impulse in a granular container composed of inhomogeneous granular chains, it is possible to confine incident impulse inside the granular container protector and to make a big solitary wave into a plurality of smaller solitary waves using the property of disintegration of an impulse at an interface. Thus, it is possible to reduce a strong impulse into many weak impulses inside the granular container protector thereby lessen the strong impulse effectively.

Problems solved by technology

Generally, it is a very important problem in a daily life to protect lives and personal properties from fatal disasters such as automobile collision, and gas explosion, etc.
However, it is practically impossible to confine the impulse in a specific region perfectly and permanently.
However, fundamental research has not been made much because of its complication and nonlinear nature.

Embodiment Construction

[0018] Hereinafter, the present invention is described in more detail with reference to preferred embodiments.

[0019] First, FIGS. 2(a) and 2(d) illustrate a schematic diagram of a standard form of the granular container protector for protecting impulse in accordance with the present invention. Further, FIGS. 2 (b), 2(c), and 2(e) illustrate schematic diagrams in accordance with the present invention in order to compare with a standard form of the granular container protector for protecting impulse illustrated in FIGS. 2 (a) and 2(d).

[0020] In FIGS. 2(a) to 2(e), circles, hatched octagons, and squares indicate p=1.5, p=2, and p=1, respectively and the ratio of mass to elastic property (i.e., m / η) is indicated as mass m of granules by setting the elasticity thereof to be a fixed value. In FIG. 2, FIG. 2(a) or FIG. 2(d) is a standard type granular container protector for protecting impulse in accordance with the best modes of the present invention.

[0021] Referring to FIG. 2, the pre...

Abstract

The present invention discloses a granular container protector for protecting impulse comprising a plurality of granular media each having a certain elastic property and a certain mass; wherein the plurality of granular media is arranged one-dimensionally into a plurality of sections, each section including one or more granular medium having same elastic property and same mass; wherein the plurality of sections is arranged in a manner that a ratio of mass to elastic property of the granular media in each section decreases toward a central section from both side sections; wherein the plurality of sections is arranged to be a mirror image about the central section; and wherein the side sections and the central section form walls of the granular container protector.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to Korean Patent Application No. 10-2005-0021244 filed on Mar. 15, 2005, which is incorporated in its entirety by this reference. TECHNICAL FIELD [0002] The present invention relates to a granular container protector for protecting impulse. More specifically, the present invention relates to a granular container protector for protecting impulse which lessens a big external impulse effectively by disintegrating it into a plurality of small impulses and releasing the small impulses little by little with time lag, using propagation characteristics of the impulse in a granular chain. DISCUSSION OF RELATED TECHNOLOGY [0003] Generally, it is a very important problem in a daily life to protect lives and personal properties from fatal disasters such as automobile collision, and gas explosion, etc. It becomes high interests in terms of an industrial aspect to lessen various kinds of mechanical impacts coming from...
