作为深海采矿水力提升系统的重要组成部分,履带式集矿机的牵引力及行走性能对深海资源的安全高效开采具有重要影响。目前,深海履带式集矿机牵引力的计算仅考虑深海底质的弹塑性,尚未考虑与时间相依的流变特性以及履带式集矿机作业时履带底部的不同接地比压(受沟壑、障碍、斜坡影响)等情形。本文通过深海模拟底质直剪流变和压-剪耦合流变的本构理论与试验研究,建立了基于不同的深海底质本构模型(弹塑性、直剪流变、压-剪耦合流变)和接地比压分布(均布、线性分布、非均布)下履带式集矿机牵引力计算模型;利用功能原理推导了相应的履带式集矿机牵引力计算公式,并分析了深海底质本构模型、接地比压分...

The tracked mining vehicle's walking performance has a great influence on the efficiency of exploiting deep-sea resources as an important part of the hydro-mechanics lifting deep-sea mining system.Currently,the calculation of mining vehicle traction force only considers the elastic-plastic performance of deep-sea sediment instead of its time-dependent mechanical performance (the more obvious rheological performance than land soil) and different grounding pressure distributions(influenced by a deep-sea mountain,ditch)under the crawler of mining vehicle.This paper mainly obtained a compression-s...
