Dynamic Analysis of Bottom Subsidence of Benthic Lander

The geomorphology of the deep-sea environment is complex, including seamounts based on hard rocks and seabeds rare soft sediments. Therefore, frame benthic lander needs to be shock subsidence resistant. In this paper, static model landers established analyze their force deformation under different loads, dynamic derive motion equation landing sediment. Some typical structure analyzed with ANSYS Workbench analysis module Explicit Dynamics module. sea trial data prototype were provide reference for design application lander’s framework. research done in paper provides basis impact resistance bottom speed proposes a simulation method calculation lander.
