Abstract

The invention discloses a testing device for measuring the impact sensitivity and friction sensitivity of an energetic material. The testing device comprises a case, a servo motor, an air pipe and a pneumatic knocking hammer, wherein an air outlet pipe orifice of the air pipe is communicated with an air inlet of the pneumatic knocking hammer in a sealed manner; a test sample impact testing cavity corresponding to the pneumatic knocking hammer is formed in the right side of the bottom of the case; an impact rod component is movably mounted in the test sample impact testing cavity, and an impact column component is arranged corresponding to the impact rod component; the servo motor, a lead screw and an ejector rod are sequentially connected; a test sample friction testing cavity is formed in the test sample impact testing cavity; a sliding column sleeve is movably mounted in the test sample friction testing cavity; a left sliding column and a right sliding column are arranged in the sliding column sleeve; an energetic material friction sensitivity test sample is arranged between the left and right sliding columns; the positions of the bottom of a piston hammer body of the pneumatic knocking hammer and the outer wall of the test sample friction testing cavity correspond to each other. The device has the characteristic of multifunction, and can be used for simultaneously testing the impact sensitivity and friction sensitivity of the energetic material.

Description

technical field [0001] The invention relates to the field of measuring the impact sensitivity and friction sensitivity of energetic materials, in particular to a testing device for measuring the impact sensitivity and friction sensitivity of energetic materials. Background technique [0002] The impact sensitivity of existing energetic materials can only be tested through the impact sensitivity testing equipment of energetic materials, and the friction sensitivity test of existing energetic materials can only be tested through the friction sensitivity testing equipment of energetic materials. The current impact sensitivity test The functions of the equipment and the friction sensitivity test equipment are relatively single. One type of equipment only has a single impact sensitivity test or friction sensitivity test function, resulting in high laboratory investment costs; the existing test equipment is large in size and heavy in weight. The anchor cannot be moved casually, an...
