Problems solved by technology

[0003] Drop tests can be performed using a drop weight testing machine equipped with guide rails to control the direction in which the ammunition falls, but the test is often limited by the space between the guide rails, and many large ammunition cannot Carry out the experiment; the method of manually lifting the energetic material to a certain height and then releasing it is dangerous, inefficient, and uncertain, and the experimental results are rough
The release of ammunition in the existing drop test machine usually adopts the method of electromagnet power off, detonator blowing the rope, and flipping the board. However, when the ele

Abstract

The invention discloses a separation device for an energetic material drop test, and relates to the technical field of energetic material experiments. The separation device for the energetic materialdrop test comprises a piston sleeve, a piston, a pressing cap, an explosive chamber, an explosion assembly, a first hanging ring, a second hanging ring and a plurality of shear pins, wherein the piston and the pressing cap are respectively installed at two ends of the piston sleeve; the explosive chamber is arranged in the piston sleeve; the explosion assembly is arranged in the explosive chamber;one end of the piston is sleeved in the piston sleeve; the other end of the piston is fixedly connected with the first hanging ring; a sealing assembly is arranged between the piston and the piston sleeve; an annular limiting groove is formed in the piston; the shear pins penetrate through the outer wall of the piston sleeve and abut against the annular limiting groove; one end of the pressing cap is fixedly connected with the piston sleeve; and the other end of the pressing cap is fixedly connected with the second hanging ring. The separation device for the energetic material drop test provided by the invention is large in bearing weight, short in separation time, good in safety, high in reliability and high in experiment precision.

Description

technical field [0001] The invention relates to the technical field of energetic material experiments, in particular to a separation device for testing energetic material drop experiments. Background technique [0002] During the production, storage, transportation and use of energetic materials, it is unavoidable to encounter unexpected stimuli such as drops and impacts. It needs to be drop tested. Usually, the packaged energetic material is freely dropped at a certain height and hits the hard surface, and the reaction level of the drop test is determined according to the reaction of the charge, the perforation and deformation of the hard surface, etc., in order to evaluate the safety and It provides a basis for formulating a crisis response plan for energetic materials in the event of falling stimulation. [0003] The drop test can be carried out using a drop weight test machine equipped with guide rails in order to control the direction in which the ammunition slides, b...
