Structure design and simulation of expendable bottom penetrator

In order to measure the bearing capacity of the deep seabed quickly and accurately, a retractable bottom penetrometer (XBP) was developed. The sampler mainly consists of probe, sealed pressure chamber, acceleration sensor, power supply, data processing system composed of five parts. In this paper, based on the existing research at home and abroad to complete the structural design of the device, according to the pressure vessel design verification formula for the pressure of the shell of the pressure of the check analysis and work with the software 7000 meters deep sea pressure simulation analysis.
