水中爆炸实验装置结构设计与防护研究

Structural design of a test facility for underwater explosion and its protection measure to reduce shock wave

为开展水中工程结构及装备的抗爆性能实验研究,设计、建造具有多种功能的水中爆炸大型实验装置。据一维弹性平面波理论,对该装置爆炸水池结构设计的主要问题及抗爆隔震性能进行分析;研究纵波入射时水池结构内部不同介质应力波传播情况与破坏模式;并运用气泡帷幕防护技术,对降低水中爆炸冲击波防护措施可行性进行初步试验研究及探讨,验证该水中爆炸实验装置结构设计的合理性,降低水中冲击波的防护措施有效性。

Here,in order to perform anti-blast performance experimental study for underwater engineering structures and equipments,a large-sized underwater explosion test facility with multi-function was design and built.The facility included an explosion cistern,a lightweight steel sliding and a lifting equipment,a reserving and pressuring equipment,a screen bed base,an underwater explosion pressure test system and a test room.Based on one-dimensional elastic plane wave theory,the main problems of the structural design and the anti-blast and anti-vibration performance of the explosion cistern were analyzed.The transmission of stress wave and the damage model of different mediums of the cistern were studied when longitudinal waves injected the explsion cistern.Using a bubble curtain technology,the feasibility of the protection measure to reduce shock wave of underwater explosion was tested and discussed.The rationality of the structural design for the facility and the effectiveness of protection measure to reduce shock wave of underwater explosion were tested and verified.
