Damage Assessment for Main-Battle Tank Gun Pipe Hit by Fragments

In order to implement components level vulnerability analysis and assessment to realize exact equipments supportability simulation during the war, the research on damage assessment model and assessment simulation method for main-battle tank hit by high explosive shell was implemented. According to damage modes and damage features, taking gun pipe as example, interaction calculation model between gun pipe and fragments produced by high explosive shell was built using analytic method, based on which program was compiled. Interaction rules between gun pipe and fragments were obtained under initial conditions of different locations and different directions. Case analysis was carried out according to interaction data and battle damage assessment model. Research results are significant to main-battle tank battle repair and precise maintenance.
