The invention discloses an equivalent test model for an explosion effect in a ship cabin. The model comprises a main cabin, an adjacent cabin, an annular supporting column, a pressure measuring hole,a shock wave pressure measuring assembly, a charging hole and a dynamic deformation measuring system, a ship multi-cabin structure is simplified into a single-cabin structure with adjacent cabin circumferential constraint, the size of each wallboard is determined according to a scaling scale of 1:4 of a prototype, the thickness of each wallboard is determined according to the scaling scale of 1: 4and a similarity criterion formed by materials and the thickness of each wallboard, and cabin reinforcement is converted into the equivalent thickness of each wallboard according to volume equivalence, strength equivalence and a certain proportion. The test model is a scaling equivalent model of a ship cabin, has the remarkable advantages that the scale is small, the manufacturing cost is low, the damage effect is basically equivalent to that of a real ship, and is suitable for ship target damage effect test and evaluation research.
本发明公开了一种舰船舱室内爆炸效应等效试验模型,包括主舱室、临舱室、环向支撑柱、压力测量孔、冲击波压力测量组件、装药孔、动态变形测量系统,其主要特点是将舰船多舱室结构简化为含临舱环向约束的单舱室结构,各壁板的尺度按照与原型1:4的缩比尺确定,板厚按照1:4缩比尺和由材料与板厚组成的相似准数确定,舱室加筋按照体积等效和强度等效并以一定比例折算为壁板的等效厚度。本发明的显著优点是试验模型是舰船舱室的缩比等效模型,尺度小、制作费用低,毁伤效果与实船基本等效,适用于舰船目标毁伤效应测试与评估研究中。
