Aiming at the matching requirements of gravity and buoyancy for the full-depth ocean underwater vehicle of Haidou in 10000 meter depth, the influence mechanism of Marine environmental factors on the change of buoyancy caused by volume change during the process of its 10000 meter depth crossing was studied, and the influence of various Marine environmental factors on the matching of gravity and buoyancy of Haidou was analyzed. Based on the mechanism analysis method, a comprehensive mathematical model of the bulk elastic modulus of the full-depth ocean underwater vehicle was constructed to provide a basis for buoyancy trim for tasks at different depths and realize its environmental adaptability to different depth profiles. Based on the sea test data of different diving depths of Haidou, the accuracy of the full-depth ocean bulk elastic modulus model of Haidou constructed in this paper is verified, and the model reference and theoretical basis are provided for the implementation plan of the underwater vehicle depth profile environment adaptability in the full-depth ocean.
