Problems solved by technology

At the present stage, the means of evaluating the ability of ammunition to target is mainly to use pressure sensors to test the overpressure peak value, positive pressure action time, impulse ( Huang Lai's method, research on the shock wave effect of temperature and pressure agents, Nanjing University of Science and Technology master's degree thesis, 2008), the disadvantage of this method is that the parameters of a certain point are tested, and the test error is very large, generally more than 10%
At present, there is no test system that can visually reflect the response energy and response impulse of the target after the shock wave after the detonation of the ammunition or explosive reaches the target after a certain distance

Abstract

The invention provides a response energy and response impulse testing system of a target. The invention is characterized in that the testing system comprises an initiation system and a data acquisition and processing system. The initiation system comprises an explosion chamber (2), a specimen holder (3) and an exploder (1). The data acquisition and processing system comprises an angle measurer (4), a swinging plate (5), a test pendulum support (6), a shaft seat (7) and a cross shaft (8). The side surface of the explosion chamber (2) is provided with holes. The system is suitable for response analysis of a damaged target and also suitable for propagation characteristic analysis of shock wave after ammunition ammunition detonation.

Description

technical field [0001] The invention relates to a target response energy and response impulse test system, which is suitable for the response analysis of the damaged target and the propagation characteristic analysis of the shock wave after the ammunition detonation. Background technique [0002] Ammunition research workers are very concerned about the response energy and response impulse of the target after the shock wave generated by the explosion of the ammunition propagates to the damaged target, because this is very important to the design of ammunition (including explosive design and warhead design, etc.). At the present stage, the means of evaluating the ability of ammunition to target is mainly to use pressure sensors to test the overpressure peak value, positive pressure action time, impulse ( Huang Lai’s method, Research on the Shock Wave Effect of Temperature and Pressure Agents, Master’s Degree Thesis of Nanjing University of Science and Technology, 2008), the di...
