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.

In this paper, mass measurement devices (MMDs) developing by the authors for use in the International Space Station (ISS) are reviewed. First, Space Balance, which is a small mass measurement device (SMMD), is reviewed. In Space Balance, the momentum conservation between two objects, the subject mass and the reference mass, are compared. Then Space Scale, which is a body mass measurement device (BMMD), is reviewed. In Space Scale, a human subject is pulled using rubber string. Force is measured using a force transducer and acceleration is measured using optical interferometer. Both Space Balance and Space Scale have shown high accuracies in the ground experiments.
