Design on Measuring Device of Extracting Bullet Force for Fixed Loading Shell

摘要

An extracting bullet force measuring device has been designed. It adopts mechanical loading and screw transmission, with a Variable Frequency Drive controlling the driving motor, maintains the test speed adjustable; using the force transducer HP-50K as the key device of force transducing and data processing, when connecting to the computer, the maximum, the average and the curve of the extracting bullet force can be drawn. The system is simple in structure and convenient in operation, can be used to measure the extracting bullet force of 37mm~100mm caliber fixed loading shell.
