摘要: The titanium alloy high-pressure chamber studied in this paper serves as a key component of the manipulator-held sampler, which has an ability in-situ pressure-retaining and used for deep-sea sediment manned submersibles. Finite element analysis (FEA) had been to analyze burst with original structure under simulated condition. Numerical results showed that was due stress concentration on top rounded surface lower section pressure chamber, so further designed eliminate concentration. After improvement, maximum principal point modified 396.672 MPa about two times smaller than (809.282 MPa). Moreover, experimental test carried out verify structure. experiment could achieve 93% ambient 60 MPa, 86.7% when exposed 71.5 MPa.
