摘要
深海海底矿产的取样调查是深海矿产资源勘探和地质调查不可或缺的步骤,目前“海龙Ⅲ”号ROV尚没有一款在复杂的富钴结壳和多金属硫化物区域实现深海矿产岩芯取样的破碎器。本文在分析深海矿床取芯特点的基础上,基于“海龙Ⅲ”号ROV的搭载特点,设计了深海矿床冲击式取样器的主要结构,对破碎器的功能指标进行了推导计算,并基于ANSYS Workbench对破碎器进行了动力学仿真模拟,仿真结果表明,破碎器可以实现预期的功能指标。
The sampling survey of deep sea seabed minerals is an indispensable step for deep sea mineral resources exploration and geological survey.At present,there is no sampler for deep sea mineral core sampling in complex cobalt rich crusts and seafloor massive sulfide in ‘Hailong III’ ROV.Based on the analysis of deep sea mineral deposit coring characteristics and the carrying characteristics of deep sea ROV,the deep sea deposit impact sampler is designed,and the functional indexes of the sampler are derived and calculated.The dynamic simulation of the sampler is carried out based on ANSYS workbench.The simulation results show that,the function of the sampler meets the design expectation.
