Problems solved by technology

The recoil movement of firearms is relatively complicated, and the recoil force is not concentrated on the axis direction, resulting in very unstable test process of recoil force. Therefore, it is required that pressure sensors with high precision and good dynamic performance should be used as much as possible during the test process of firearm recoil force. Reasonable and firmly installed test platform, but the accuracy and sensitivity of the current firearm recoil measurement system are relatively low, which cannot meet the test requirements

Abstract

The invention relates to an interaction force measuring device of a human-gun system. The interaction force measuring device comprises a recoil force testing platform, a force sensor and a sensing system signal processor. The recoil force testing platform comprises clamping fixtures, and a spring damping mechanism is arranged between one clamping fixture and a gun. The force sensor is arranged between the recoil force testing platform and a gunstock. The motion force of the gun is collected by the force sensor and sent to the sensing system signal processor. The sensor comprises an X-direction differential capacitor unit assembly and a Y-direction differential capacitor unit assembly. The X-direction differential capacitor unit assembly and the Y-direction differential capacitor unit assembly each comprise two or more capacitor unit modules forming differential motion. The force measuring device is used for tests for analyzing recoil energy, muzzle brake efficiency and other parameters after collecting the recoil force of the gun.

Description

technical field [0001] The invention relates to the technical field of motion analysis, in particular to a device for measuring the interaction force of a man-gun system. Background technique [0002] The recoil force of a firearm is the force applied by the weapon to the support or the human body during shooting. This force will cause the elastic deformation of the support, so that the firearm will also be displaced accordingly, causing changes in shooting accuracy. Therefore, the magnitude of the recoil force directly Affecting the shooting accuracy and shooting stability of firearms is one of the important parameters of firearm performance. The firearm recoil motion parameter test system is used to complete the test of recoil force, recoil energy, brake efficiency and other parameters. The recoil movement of firearms is relatively complicated, and the recoil force is not concentrated on the axis direction, resulting in very unstable test process of recoil force. Therefore...
