摘要
为分析深海采矿作业车在稀软底质表面行走时自身沉陷以及与底质的法向粘附力的触底特性,通过室内小型底板代替作业车底部触底部件,开展了作业车触底沉陷特性以及法向粘附特性试验。结果表明,压陷量随接地比压增大而增大;长宽比较大的底板压陷量明显大于长宽比较小的底板。粘附力与底板面积呈现较好的线性关系,相关系数R2=0.94,回归直线的斜率为894.56 N/m2。
Aiming at the mining vehicle's sinking into soft sediment on the seafloor and normal adhesion force of polymetallic nodule mining vehicle during seabed operation, laboratory tests were conducted to investigate the mining vehicle's sinking and normal adhesion features by using a small-sized plate substituting parts on the bottom of vehicle sinking into the simulated sediment. Results showed that sinking of the sediment increased with an increase in the ground pressure, and the bottom plate of the vehicle with a larger aspect ratio led to deeper sinking than the bottom plate with small aspect ratio. And the adhesive force is in a good linear relationship with the floor plate area, with a correlation coefficient R^2=0.94 and the slope of regression line calculated to be 894.56 N/m^2.
