Automatic Measuring Device

The powder chamber of cannon gun tube was an important indicator which affected gun performance. The accuracy of fire, precision and the other technical indexes were inevitably affected by the chamber geometry parameters directly or indirectly. So the detection of cannon gun tube was an important part in the whole gun detection technology. This paper introduced the structure and the measuring principle about diameter automatic measurement device of cannon gun tube and made a prototype. Then the experimental verification was carried out. The experimental results showed that the automatic measuring device had the advantages of simple principle, convenient operation, high precision, and had a certain popularization value in use.

Automatic Measuring Device

The paper introduced the status quo of the gel pen smoothness; developed a new measuring device - smoothness tester for the status quo of the inaccurate measurement; described the measuring principle and system design of the smoothness instrument. Experimental data showed the superiority of the measurement. It basically solved the inaccurate measurement situation. The repeatability is less than 15%, and the correlation with the feeling is not more than 2%.
