摘　　要：本文通过对耙吸挖泥船吊放系统的载荷特点及其其与船体连接处的受力情况分析,探讨了有限元法校核连接处结构强度和局部振动性能,总结了工程船此类特殊设备的加强结构设计和计算校核方法。作为耙吸挖泥船作业的重要辅助设备,吊放系统必须安全、可靠,与船体连接有足够的强度和刚度,能满足频繁吊放耙管的需求。研究吊放系统的加强形式和强度校核方法,可为工程船特殊设备的船体加强区域的结构设计提供实用的参考。In this paper,through the analysis of the load characteristics of the hoisting system of the trailing suction dredger and the force at the connection with the hull,the structural strength thereof and local vibration performance verified by way of the finite element method are discussed,and the reinforcement structure design and calculation verification methods of such special equipment of engineering ships are summarized.As an important auxiliary equipment for the operation of trailing suction dredger,the hoisting system must be safe and reliable,and be connected with the hull by sufficient strength and rigidity to meet the needs of frequent hoisting of rake pipes.The study of the reinforcement form and strength verification method of the hoisting system can provide practical reference for the structural design of the hull reinforcement area of the special equipment of the engineering ships.
