摘　　要：为考查全海深载人潜水器载人舱球壳在交变海水压力作用下的结构长期安全性,项目中共设计2只钛合金缩比球壳在深海环境模拟装置内开展疲劳试验。为降低对深海环境模拟装置的损伤并有效缩短试验时长,提出了一种超高压深海环境下采用内外压差法开展的双球并行疲劳试验技术,并据此进行了近7000个循环周期的加卸载试验。结果表明,该试验技术长期有效可靠,可为同类型试验提供技术依据和应用参考。In order to investigate the long-term structural safety of the manned capsule shell of deep-sea manned submersible under the action of alternating seawater pressure,two titanium alloy shrinkage spherical shells are designed to carry out fatigue test in a deep-sea environment simulator.In order to reduce the damage to the deep-sea environment simulation device and effectively shorten the test time,a dual-ball parallel fatigue test technology using the internal and external pressure difference method in ultra-high pressure deep-sea environment is proposed in the paper,and the loading and unloading test of nearly 7000 cycles is carried out accordingly.The results show that the test technology is long-term effective and reliable,which can provide technical basis and application reference for the same type of tests.
