Problems solved by technology

[0004] The main methods of testing the blast shock wave are: equivalent target method, electrical measurement method, theoretical calculation method, etc. The equivalent target method can reflect the damage effect of the shock wave on the corresponding distance to the building to a certain extent, but it cannot accurately reflect the explosion field. parameter
Theoretical calculation method can only be calculated for traditional single explosives, and it is difficult to calculate and analyze the interference factors brought by ammunition with complex structure, cartridges and complex operating environment, which has great limitations

Abstract

The invention aims to provide a tubular close-range shock wave tester which can be used for field data testing of various engineering constructions and blasting tests, and provides accurate shock wave parameters for research of ammunition shock wave damage capability and feasibility analysis of various engineering blasting safety assessment. The device specifically comprises a composite cushioning material (1), a pressure sensor (2), a supporting beam (3), a signal processor (4), an information memory (5), a power supply device (6), a start button (7), a device base (8), a switch (9), a connecting bolt (10), a metal shell (11) and a tubular receiver (12). The whole device is wrapped by a metal shell, a built-in cushioning material has high resistance to interference factors such as clutters, lateral waves and electromagnetic waves, and shock wave parameters in a blasting field are measured and stored through an electric measurement method.

Description

Technical field: [0001] The invention relates to the field of blasting testing, in particular to a tubular short-range shock wave tester, which can be used for on-site data testing of various engineering constructions and blasting tests. Background technique: [0002] In today's complex international environment, regional conflicts are becoming more and more prominent, and in the face of increasingly complex peripheral issues, to have a say in the world, national defense and military forces are the top priority of development. In the military, the ability of ammunition to damage the target is an important indicator to measure the military level. Generally, the damage work done by ammunition to the target is divided into fragmentation effect and shock wave damage. Therefore, it is particularly important to measure the shock wave generated by the ammunition to measure the power of the ammunition and provide a reference for the design of the ammunition. [0003] For domestic ...
