Abstract

The invention relates to an explosion shock wave test and damage evaluation technology, and particularly relates to a surface shock wave test device and an evaluation method in an explosion environment. According to the invention, a problem that the test result and the damage evaluation result of the existing explosion shock wave test and damage evaluation method are inaccurate is solved. The surface shock wave testing device in the explosion environment comprises a closed cavity, a supporting stand column, a flexible substrate, a flexible covering layer, four pressure sensors, a wireless data recorder, four wires and a computer, wherein the closed cavity is a cylindrical structure; the supporting stand column is vertically fixed to the center of the outer bottom surface of the closed cavity. the flexible substrate is a strip-shaped structure; the flexible substrate is hooped in the middle of the outer side surface of the closed cavity, and the two ends of the flexible substrate are sewn together; the flexible covering layer is the strip-shaped structure; and the flexible covering layer is arranged on the outer side surface of the flexible substrate in a hooping mode, and the two ends of the flexible covering layer and the outer side surface of the flexible substrate are sewn together. The device is suitable for explosion shock wave testing and damage evaluation.

Description

technical field [0001] The invention relates to explosion shock wave testing and damage evaluation technology, in particular to a surface shock wave testing device and evaluation method in an explosive environment. Background technique [0002] In the explosion tests that need to evaluate the lethality (such as the damage effectiveness evaluation test, the ammunition static explosion power test, etc.), the experimental sheep is usually used as the test object, and the blast shock wave test and damage evaluation are performed on the test object. At present, the explosion shock wave test and damage assessment are mainly realized through the following methods: On the one hand, the explosion shock wave test is carried out by using the indirect test method. The shock wave pressure, and then estimate the explosion shock wave pressure on the surface of the test object according to the measurement results, thus realizing the explosion shock wave test. On the other hand, the general...
