INVESTIGATE THE EFFECT OF THE THROTTLING RING WEAR ON THE MOVEMENT OF THE ARTILLERY ON THE TANK WHEN FIRING

Abstract

Artillery weapons in general and the artillery types on the tank in particular,
after long-term use, some parts on the cannon will be worn out due to friction,
and impact, especially the details that need high precision such as the throttling
ring and the throttling rod. In this paper, a mathematical model is established to
evaluate the influence of the change in diameter of the throttling ring on the
reliability of artillery when firing. Numerical calculation applied to the 100mm
artillery on the T55 tank. The calculation results show that: The law of recoil
braking force is changed when the diameter of the throttling ring dR is greater
than 38.5mm, then the maximum pressure in the cavity 1 decreases suddenly by
16.6%. This is undesirable to maintain the stability of the cannon on the tank
when firing. The results of the article contribute to re-evaluating the tactical and
technical features of the cannon to propose a plan to preserve, maintain, replace,
and improve the service life of the weapon in combat.
