EXPERIMENTAL INVESTIGATION AND DETERMINATION OF FORCES ACTING ON THE RECOILING MASS FOR THE CALCULATION, DESIGN, AND FABRICATION OF AN ARTIFICIAL RECOIL DEVICE FOR GROUND ARTILLERY

Abstract

The experimental research process determined the dimensional parameters of the recoil braking unit and the counter-recoil (recuperator) unit; identified the initial and final counter-recoil forces of the recuperator; and established the variation law of the regulating rod diameter with respect to the recoil length, which provides a basis for calculating the recoil resistance force of artillery during artificial recoil operation. The calculated recoil resistance forces are presented in both graphical form and tabulated characteristic parameters, showing the minimum and maximum values of the recoil resistance force for two types of ground artillery, namely the 85 mm D-44 and the 152 mm D-20, at different elevation angles in accordance with the prescribed artificial recoil conditions. The research results clearly indicate that the maximum recoil resistance force for each artillery type decreases as the elevation angle increases. Specifically, when the elevation angle of the 85 mm D-44 gun increases from 0° to 25°, the maximum recoil resistance force decreases by 6.59%, whereas for the 152 mm D-20 gun, the maximum recoil resistance force decreases by 14.14% as the elevation angle varies from 0° to 45°. Furthermore, the study determined the maximum recoil resistance force to be used as the basis for the calculation and design of artificial recoil devices for ground artillery, with a value of 143.439 kN corresponding to the artificial recoil of the 152 mm D-20 gun at an elevation angle of 0°.
