Description
Technical field
The invention belongs to measure, technical field of measurement and test, and in particular to a kind of friction sensitivity automatization test system.
Background technology
In priming system industry, it is required for rubbing to energetic materials such as priming systems researching and developing, producing, detect each stage
It wipes and tests to test it, demarcate.It needs batch to be tested to be fixed pivot angle fixation pressure friction test during for testing,
It is whether qualified to test the batch sample；And when being demarcated, then needing to be fixed characteristic pivot angle under pressure tests, according to examination
Sample adjusts next pendulum angle whether explosion, to test out sample pendulum excitation angle.For testing or demarcating, put
Hammer dropping process should be similar to free circular motion, and be required for accurately testing out the speed and energy of instant of detonation pendulum,
For explosion with otherwise needing through comprehensive descisions such as light, sound, gases.
At present, domestic priming system friction sensitivity experiment still carries out in traditional pendulum type friction sensitivity test equipment,
Using manually medicine is put, hammer is manually carried, manually determines to carry clavicorn degree, full pressure pressure, the judgement of test result are given by hydralic pressure gauge
Method is to judge that explosive sound and eye-observation explosion are bright by human ear.This method measurement error because of people, because when due to different, randomness
It is larger, and its result of the test can only be qualitatively judged and can not be quantified or even many times acousto-optic unobvious, caused to judge by accident, be caused
There are hidden danger during the use of priming system, and testing crew, always in testing ground, personnel labor intensity is big, safety
It is low.
Whether sample explodes, and needs are artificial to be judged, using human ear judgement explosive sound, eye-observation explosion is bright and people smells
Test gas differentiates, measurement error because of people, because when due to it is different, randomness is larger, and test gas also has harmful ingredient,
Long Term Contact can cause harmful effect to human body.
