Problems solved by technology

[0003] At present, the explosives used in complex environments are mainly non-ideal explosives, and the performance evaluation mainly adopts the static explosion test in an open space. This test has two shortcomings: First, the open experimental environment does not match the real complex environment. , the experimental results cannot evaluate the actual effectiveness of this type of explosive in a complex environment; the second is that the working principle does not match, the damage of modern explosives is mainly caused by shock waves, and the notable feature of non-ideal explosives is that the afterburning effect has a strengthening effect on the leading shock wave , the existing open test environment cannot effectively characterize this characteristic of non-ideal explosives
In addition, because the natural complex environment is difficult to find directly, and the natural environment will be damaged after a single explosion test, this may bring uncertainty to the screening of explosives

Abstract

The invention discloses an environment simulation device for evaluating the explosive blast wave performance of a non-ideal explosive. The device comprises parts such as a first straight branch pipe, a second straight branch pipe, a straight delivery pipe, a baffle plate, an inclined branch pipe, a third straight branch pipe and the like. According to the device, each part is connected through flanges, and the explosive can explode at a certain distance in the pipes during a test; explosive blast wave overpressure parameters of the non-ideal explosive are measured to screen explosives for a complex combating environment.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and relates to a set of mechanical devices, in particular to a combined complex environment simulation device for evaluating the performance of non-ideal explosive explosion shock waves. Background technique [0002] As a natural barrier, the complex environment or terrain can improve the survivability of the target, and it is one of the effective measures against tactical missile strikes. The development of modern damage technology requires the output performance of explosives to match the environment, so the evaluation technology of explosives used in complex environments has always been a hot and difficult point of research at home and abroad. [0003] At present, the explosives used in complex environments are mainly non-ideal explosives, and the performance evaluation mainly adopts the static explosion test in an open space. This test has two shortcomings: First, the open exp...
