The invention discloses a device and method for testing the
power capability of composite explosives. The device for testing the
power capability of the composite explosives is composed of winches, supports, support supporting rods, bearing bases, rotary shafts, swing arms,
pendulum bobs,
pendulum bob protruding teeth, a one-way
limiter and angulometers. Before a test, explosive samples to be tested are prepared through special pressing molds, the samples to be tested are placed in inner cavities of the
pendulum bobs and detonated through detonators, after
detonation, the two pendulum bobs swing circumferentially around the rotary shafts under the limitation of the swing arms, the pendulum bobs are controlled by the one-way
limiter and the pendulum bob protruding teeth to swing to the highest point and then stay still, the angulometers are used for measuring the swing angles of the pendulum bobs, and the
power capability of the composite explosives after
detonation is calculated and measured through the swing angles of the two pendulum bobs. According to the device and method, the improvement is made on the basis of a traditional ballistic trajectory
mortar method, the conversion efficiency for converting
chemical energy into
mechanical energy of
detonation can be improved through the two-pendulum-bob structure, and therefore the test result and the
quantitative expression of the power capability of the composite explosives are more accurate.
