Description

technical field [0001] The invention belongs to the technical field of measurement and testing, and in particular relates to an automatic testing system for friction sensitivity. Background technique [0002] In the pyrotechnics industry, it is necessary to conduct friction tests on energetic materials such as pyrotechnics for testing and calibration in all stages of R&D, production, and testing. When used for testing, it is necessary to conduct a fixed pendulum angle and fixed pressure friction test on a batch of samples to test whether the batch of samples is qualified; while for calibration, it is necessary to perform a characteristic pendulum angle test under a fixed pressure. No Adjust the angle of the next pendulum to test the excitation angle of the pendulum of the sample. Regardless of whether it is used for testing or calibration, the falling process of the pendulum should be similar to free circular motion, and it is necessary to accurately test the speed and ener...

Problems solved by technology

The measurement error of this method varies from person to person and from time to time. The randomness is large, and the test results can only be judged qualitatively and cannot be quantified. In many cases, the sound and light are not obvious, resulting in misjudgment and hidden dangers in the use of pyrotechnics. , and the test personnel are always at the test site, the labor intensity of the personnel is high, and the safety is low

[0004] Whether the sample explodes needs to be judged manually. The human ear is used to judge the explosion sound, the human eye observes the explosion light, and the human smells the test gas to judge. The measurement error varies from person to person and from time to time. The randomness is large, and the test gas is also harmful to the human body. ingredients, long-term exposure will cause adverse effects on the human body
