The invention discloses a pressure-bearing sealing bay vibration damping structure which mainly comprises an elastic vibration damping assembly and a damping assembly, the elastic vibration damping assembly comprises a plurality of metal rubber vibration dampers evenly arranged around the bulkhead, the metal rubber vibration dampers are connected between the bulkhead and a ship body, and therefore elastic vibration damping is achieved; the bulkhead sealing assembly comprises a metal corrugated plate, the metal corrugated plate is connected with the bulkhead and the ship body in a sealed mode through an upper sealing fastener and a lower sealing fastener, and therefore bulkhead sealing and bulkhead displacement compensation are achieved. According to the bulkhead vibration reduction structure, overall vibration reduction of the bulkhead wall can be achieved, the vibration reduction effect is good, meanwhile, the requirement for the overall size space is lowered, and pipeline arrangement on the bulkhead wall is not affected; the metal corrugated bent plate and the O-shaped ring are combined, so that the sealing effect is good, the safety is high, meanwhile, the short-time high-temperature use requirement can be met, the overall strength and rigidity of the aircraft are guaranteed, cabin isolation and pressure-bearing sealing are achieved, and the engineering applicability is high.
本发明公开了一种承压密封隔舱减振结构,主要包括:弹性减振组件,包括围绕舱壁均匀布置的若干金属橡胶减振器,所述金属橡胶减振器连接于舱壁和船体之间,由此实现弹性减振;隔舱密封组件,包括金属波纹板,所述金属波纹板通过上密封扣件、下密封扣件分别与舱壁和船体密封连接,由此实现隔舱密封和舱壁位移补偿。本发明的隔舱减振结构可实现舱壁整体减振,减振效果好,同时降低了对总体尺寸空间的需求,不影响舱壁上管路布置;采用金属波纹曲板与O型圈组合,密封效果好,安全性高,同时可满足短时高温使用要求,保证航行器整体强度刚度,实现舱室隔离和承压密封,具有很强的工程适用性。
