Abstract

The invention discloses a sleeve rod type artillery recoil machine based on STF and a working method, and belongs to the technical field of recoil machines and the field of dampers. The sleeve rod type artillery recoil machine comprises an outer cylinder, an inner cylinder, a recoil rod, a compensation rod and a recoil piston; the inner cylinder is sleeved with the outer cylinder, an annular cavity is formed by a gap between the inner cylinder and the outer cylinder, and the annular cavity is filled with shear thickening liquid; the recoil piston is arranged in the inner cylinder, one end of the recoil piston is connected with the recoil rod, the other end of the recoil piston is connected with the compensation rod, and the recoil rod and the compensation rod both extend out of the inner cylinder; the recoil piston divides the inner cylinder into a working cavity and a compensation cavity, and the working cavity and the compensation cavity are both filled with shear thickening liquid; and the two ends of the inner cylinder are sealed through end covers, a plurality of liquid flowing holes are formed in the end covers, and the two ends of the outer cylinder are sealed. Compared with a traditional recoil machine, the recoil machine has the beneficial effects that the number of cavitation bubbles appearing in the compensation cavity when the traditional rod type recoil machine is recoiled is reduced so that counter-recoil force can be better consumed during counter-recoil, and counter-recoil displacement is controlled.

Description

technical field [0001] The invention relates to the technical field of retreating machines and the field of dampers, in particular to an STF-based sleeve rod artillery retreating machine and a working method. Background technique [0002] The artillery retreat machine is an important part of the artillery anti-recoil device. It consumes the recoil and recoil energy of the artillery by making the recoil fluid absorb energy or release energy, and controls the recoil and recoil of the artillery within a certain length and time. And control the force and movement law of the artillery when it recoils and recoils, and improves the shooting accuracy. Therefore, in actual artillery combat, the retreating machine plays an indispensable role. [0003] For the current artillery retreating machines, most of them use ordinary petroleum-based retreating fluids and glycerin-based retreating fluids. Previous studies have found that due to the high-speed flow of the retreating fluids, ordin...
