基于ABAQUS的重力活塞取样器理论分析与研究(英文)

Analysis and Research on the Gravity Piston Corer Theory Based on ABAQUS

首先对重力活塞取样器贯入沉积物的过程及其影响因素进行分析,建立了取样器贯入深度理论模型,得出取样器贯入深度计算方程与影响因素。然后通过ABAQUS有限元软件对取样器贯入过程进行分析,并与国家海洋局第一海洋研究所提供的深海沉积物实验数据进行对比,验证了理论模型的正确性。为深海重力活塞取样器的进一步研究提供了有力的理论支持。

The process of gravity piston corer penetrating into sediment was analyzed and the in- fluence factors for this process were comprehensively discussed. The sampler penetration depth theory model was established and the calculation equation of penetration depth was obtained. Based on the ABAQUS finite element software, the sampler penetration process was numerically analyzed. The theoretical model was verified by the experimental data from 20m-gravity pJston sampler deep sea sediment sampling experiments taken by First Institute of Oceanography State Oceanic Administration. Therefore, this paper provides a powerful theory which supports for the further study of abyssal gravity piston sampler.
