The Study Of A Measurement For Couple Arm Of Force

The couple arm of force refers to part of the mass center of the location of the bore axis vertical distance. The size of couple arm of force is a direct impact on the stability of artillery fire, as artillery fire, the chamber together at the end of the role of line did not pass artillery recoil part of the mass center, it will generate a turnover moment, part of the recoil as a whole is extremely stable artillery unfavorable. Measurement of dynamic dual-arm is to determine the measured dynamic dual artillery arm of the actual location to check their compliance with technical requirements.In this paper, a data access on the basis of the development of application-specific fixtures powered dual-arm measurement technology programs; introduced Centroid measurement method used in dynamic dual arm testing process; the adoption of the Internet search and a large amount of literature, in the this article focuses on the measuring method of torque powered dual-arm methods at home and abroad there is no relevant reports, and its principle is simple, feasible, the test method is simple and easy to operate, dual-arm on the follow-up dynamic measurement system work a high reference value.
