Abstract

The invention discloses a shock wave energy and impulse integrated measuring device and method based on gradient foam, and aims to solve the problem that the existing measuring technology is complex in cable connection, needs power supply and is not suitable for extreme environments. The measuring device is composed of a shell, a gradient buffer assembly and a positioning ring. The gradient bufferassembly fills the inside of the shell. The positioning ring is fixed to the open end of the shell. The gradient buffer assembly freely moves in the shell in the axis direction. The gradient buffer assembly is formed by sequentially, coaxially, seamlessly and tightly bonding a front slider, a low-density foam layer, a first partition plate, a medium-density foam layer, a second partition plate, ahigh-density foam layer and a stop plate. According to the measuring method, the explosive shock wave energy and impulse are calculated according to the plastic deformation generated when the front slider compresses the gradient buffer assembly during explosion and the energy and impulse sensitivity coefficients of the low-density foam layer, the medium-density foam layer and the high-density foam layer. According to the invention, explosion field shock wave parameter measurement in a severe environment can be realized.

Description
