Objectives Aiming at the urgent need for research on vulnerability analysis methods for ship targets, a vulnerability analysis method for supply ship targets under anti-ship missile strikes is proposed.
Methods Taking a typical supply ship target as the research object, anti-ship missile were selected as strike weapons, and the structure-activity relationship of the target was analyzed. The dynamic response of the supply ship under the action of anti-ship missile internal explosion load was obtained through numerical simulation. The damage and damage criteria of key components under the action of anti-ship missile internal explosion load were studied, and the function damage degree of the supply ship was obtained. The target vulnerability of the replenishment ship is analyzed, and the attack method that causes the maximum damage to its navigation function is determined.
Results A vulnerability analysis method flow has been formed, which includes analysis of target structure-activity relationships, damage modes of key components, damage criteria and criteria, and then the degree of target functional damage. Based on the vulnerability distribution information, the target should be targeted at the location where non redundant components are concentrated to strike, achieving the goal of causing maximum range damage.
Conclusions This can provide technical support for future research on ship target vulnerability.
