The invention relates to a testing cable sealing device for a container for simulating a deepwater environment explosion test. According to the technical scheme, two to fifteen cable holes (8) are formed around the center of a flange cover plate (1) and located in a protection cover (2); each cable hole (8) is a through hole which is formed by three sections, the hole diameter of the upper portion is larger than the hole diameter of the lower portion, a sprue (7), sealant (6) and a ring washer (5) are concentrically arranged on the middle section of each cable hole (8) from bottom to top, each compression bolt (4) is fixedly connected with the upper section of the corresponding cable hole (8) through threads, and the lower end of each compression bolt (4) is tightly pressed on the upper plane of the corresponding ring washer (5); a testing cable (3) sequentially penetrates through the protection cover (2), the corresponding compression bolt (4), the corresponding ring washer (5), the corresponding sealant (6) and the lower section of the corresponding cable hole (8) to be connected with an underwater impact wave pressure sensor. The testing cable sealing device is high in compression resistance, good in sealing performance, easy to assemble, wide in application range, and capable of meeting the requirement for simulating the 0.01-Kg TNT equivalent explosion test at the 200 m underwater environment.

The invention relates to a pourable high-energy insensitive explosive and a preparation method thereof. Aiming at the problem of low energy level of traditional butylated hydroxyl poured PBX explosives, the present invention introduces an energetic binder and an energetic plasticizer as a binder system. By adding High-energy explosive and metal fuel components, the prepared pouring type PBX explosive has higher energy characteristics, and the density of the explosive formula is greater than 1.85g / cm 3 , the detonation velocity is greater than 7800m / s, and the explosive power is more than 1.9 times the equivalent of TNT. At the same time, the explosive formula has good low fragility, especially the mild reaction during the slow cook-off test, and the reaction level does not exceed deflagration.

Embodiments of the present invention provide a method and device for evaluating the damage effect of an explosion shock wave. By obtaining environmental model parameters and human body model parameters, and obtaining the explosive category, explosive name and explosive quality, according to the explosive category, explosive name and Calculate the mass of the explosive to obtain the TNT equivalent of the explosive, and obtain the radius of the explosive according to the TNT equivalent of the explosive; input the environmental model parameters, human body model parameters and the radius of the explosive into the K file of the ANSYS / LS-DYNA software to obtain Target calculation file; then call ANSYS / LS-DYNA software to calculate the target calculation file according to the total time of calculation and solution and the number of ANSYS / LS-DYNA cores, and evaluate the damage level of each part of the human body according to the calculation results. The method and device can automatically create and obtain different explosion environments according to parameterized settings, are used to simulate human body damage in different explosion environments, and can intuitively, accurately and efficiently evaluate the damage to the human body caused by blast shock waves.
