Abstract:
T his paper w ith the help o f a method of dynamics of a mult i-rigid-body system, this paper established fo r the f ir st t ime the dy namic model and mathemat ic model of ammunition belt links. It has four deg rees f reedom in a link. Ammunitio n belt links w ere combined w ith automat ic machine of ant i-aircraft gun to numerically simulate computatio n, and it makes a real descr ipt ion o f the law of ammunit ion belt links in mot ion , change tendency of ammunit ion belt links feed resistance. On the basis of the mathermat ic simulatio n, various factors having an effect o n the resistance were analyzed, and the major facto rs w er e carried out adjustmen under the condit io n of g uarantee to have stable f requency of f ire of the automat ic machine. T he ef fect of the r esistance on mot ion circulat io n of the automatic machine w as minimized.
