19m双体作业船总体设计+CAD图纸

菜单

摘要作业船广泛作用于港口建设、海洋开发、海洋利用等许多领域，与普通的运输船相比，具有其独特性。在地区或者全世界的海上运输行业、作业行业、勘探行为等工作中发挥的特性是一般船舶所没有的，在新兴的船舶发展中具有较高的地位和领导力。但在我国这类船舶的设计发展较晚，技术水品相对落后。58572

近年中，在军用和民用市场中双体船逐渐占据了较大的份额。它们所具有的独特的外观，特有的性能，使其被越来越多的人所认知。典型的双体船由两个瘦长的单体船（称为片体）组成，上部用甲板桥连接，体内设置动力装置、电站等设备，甲板桥上部安置上层建筑，内设客舱、生活设施等。高速双体船一般是把船体分为两个单一片体，这样就是的片体变得更瘦长，从而减少了行波阻力，使得其具有较大的航速；一般双体船的船宽要比单体船大，这使得其稳定性相对更好一点；由于双体船具有操纵性好，阻力峰不明显，使得它在军用船舶上也有较大的应用。而19m长度的双体作业船相对于其他长度的在性能、材料建造、应用上具有相应的优势，相对于其他的类型，更能被设计方或船厂所能接受。

此次设计的方法是常用的母型船改造法，在研究设计过程中参考谢云平等老师编写的《船舶设计原理》、盛邦中等老师编写的《船舶原理》、杨永祥等老师编写的《船体制图》。设计步骤简要分为：收集所要设计研究的关于双体船的研究资料，确定研究方向，寻找性能和结构优秀的船型作为母型船;在母型船的基础上进行合理的改造，确定相应的主尺度，从而完成新船总布置草图的完成;采用MAXSURF设计软件对设计船进行设计建模并通过完成的模型导出设计船的型线图;进行设计船舶的静水性能分析以及相关计算;进行设计船的稳性及干舷的相关计算;进行设计船相关的阻力计算，确定设计船的螺旋桨参数和实际航速，选择适合设计船的推进装置;整理完善所要求完成的毕业论文。

Abstract Workboat broad role in port construction in many areas of marine development, marine utilization, compared with the conventional transport ship, with its uniqueness. Plays a general transport ship features lacking in the region and around the world maritime transport, operations, exploration and other work, is a new high-performance vessels larger vessels prospects. But our boat is designed for research work late, technology is weak.

In recent years, more and more catamarans occupy the civil and military ship market. Their novel appearance and unique comprehensive performance have attracted worldwide attention. Typical catamaran by two slender single hull (known for sheet body), with the upper deck bridges connected in the in vivo setting power plant, power plant equipment, deck bridges on the upper part of the resettlement of the superstructure, is arranged in the cabin, living facilities and so on. High speed catamaran due to a single hull is pided into two pieces, each piece body more slender, thereby reducing the wavemaking resistance, so that it has high speed, at present its speed has been generally achieved 35-40 knots; the width of the catamaran is much greater than a single ship, the stability is obviously superior to ship, and has the ability to withstand strong wind and huge waves of; catamaran has not only good maneuverability, but also has the resistance peak is not obvious, the loading capacity, and so on, so it is widely used in military and civil ships in the world. And 19m length of catamaran ship operating with respect to other length built in materials properties, and application with respective advantages, compared with other types, can be designed or shipyard can accept.
