Analysis of the equilibrator moment during the artillery movement

Abstract

The artillery equilibrator is a device used to balance the gravity moment of the landing part on the trunnion. The analysis and design of the traditional equilibrator mainly considers the horizontal working state of the artillery. However, when the artillery is fighting during travel, the attitude of the vehicle will constantly change. When the artillery barrel is stably pointing at the target, the change of the attitude of the vehicle will cause the elevation angle of the barrel relative to the vehicle to change continuously, resulting in the constant change of the output torque of the equilibrator, which is very different from the horizontal work of the artillery. In this paper, the torque characteristics of the equilibrator during the artillery travel are theoretically analyzed, and the torque characteristics of the equilibrator are verified by simulation.
