摘要 在航道疏浚和大型海洋工程建设的背景下,从现有的传统疏浚技术不能满足市场需求出发,提出抓斗平挖的问题.通过对疏浚抓斗在传统操作方式下挖掘曲线的建立和分析,构建了抓斗的平挖运动数学模型,以抓斗刃口的水平运动为约束条件,反向推导得出抓斗平挖控制策略,并对此控制策略进行了运动学仿真验证.结果表明,疏浚抓斗平挖运动控制策略在抓斗挖泥船的平挖作业上具有有效性及准确性. Under the background of waterway dredging and large marine engineering construction,existing traditional dredging technology can not meet the market demand.Therefore,the problem of intelligent flat dredging is proposed.By establishing and analyzing the dredging clamshell excavation curve in the traditional way,the flat dredging mathematical model is constructed,developing the flat dredging control scheme in reverse and checking the results by kinematics simulation with the constraint condition of clamshell edge dredging flat.The results show that the flat dredging control scheme of clamshell dredger is effective and accurate in flat dredging operation.
