| 摘 要： | 耙吸式挖泥船是航道与水下沟槽开挖、航道疏浚与水下挖泥等工程中广泛采用的施工设备,深水及复杂作业环境下耙吸式挖泥船的挖掘精度控制是挖泥船施工作业需解决的重要问题.在考虑风、浪、流、船舶操作力、海床反力、波浪补偿器及其滞后等影响因素的情况下,建立了耙吸式挖泥船与耙头耦合运动的数学模型,并用实船测试数据对数值模型进行检验.通过实例计算,研究不同水深和不同风、浪、流等环境因素对耙头运动的影响,为挖泥船—耙头运动的预测及超深、超宽开挖控制提供了依据.

| Abstract: | Trailing Suction Hoper Dredger(TSHD) is widely-used equipment in construction of channel,underwater tunnel and waterway dredging engineering.Under deepwater and difficult circumstances,dredging accuracy control of TSHD is an important issue to be solved.Considering wind,wave,current,ship maneuvering force,seabed reacting force,swell compensator and its lag,as well as other combined influencing factors,a mathematical model of the coupled motion of TSHD and draghead is built,which is tested and verified by re... |
