Zhang, Y.; Ding, Z.; Wang, Zhao, Q., and Qin, S., 2019. Determining the damage mechanisms for buoyancy materials of deep-sea manned submersibles. Journal Coastal Research, 35(5), 996–1002. Coconut Creek (Florida), ISSN 0749-0208.Deep-sea submersibles are important platforms ocean exploration, their structural reliability is critical to personal safety crew. In particular, vital parts because they provide necessary submersible operations. This paper first describes overall used in Jiaolong that accumulated over a large number research expeditions during years services. The causes analyzed by computational fluid dynamics (CFD) methods. Because Jiaolong's secured its frame bolts, external forces act on concentrated these bolts. Those include wave when it floats sea surface material shrinkage occurs changes environmental pressure temperature submarine Finally, several suggestions provided improving design operation
