【摘要】：随着现代化船舶逐渐向高速化、大型化、专业化方向发展,传统的柴油机直接推进方式的船舶的缺点逐渐显现。我国领海辽阔,海洋资源丰富,开采这些资源需要各种性能优良、功能特殊的船舶,同时船舶作为航运业的主体,其自身性能的优劣同样会对行业的发展造成影响。液压传动具有功率质量比大、过载安全性好等特点,将液压马达安装在可360。回转的吊舱中,利用液压马达转动驱动螺旋桨,这样就形成了吊舱式液压推进系统。吊舱式液压推进系统兼顾液压传动的优点,同时可实现矢量推进,成为新型的船舶推进方式。本文针对一艘2320t海事公务船进行液压推进系统设计。根据提供的船型参数,本文利用泰洛法对船舶阻力进行了估算,并根据阻力估算结果进行了系统的设计。在螺旋桨初步设计中,利用MATLAB编程计算得到螺旋桨最佳转速、螺距比、敞水效率,替代了常规的图谱设计法,提高了设计效率。在系统设计环节,通过计算,确定系统关键元件的性能参数,并结合REXROTH公司的产品进行了选型,绘制液压推进系统原理图。利用功率键合图理论对系统进行建模,推导系统各个子模型的状态方程,为系统仿真奠定理论基础。采用基于键合图理论的LMS AMEsim软件对系统性能进行仿真,从泵控信号、管路布置、负载等几个方面分析了外界因素对系统性能的影响。
[Abstract]:With the development of modern ships towards high speed, large scale and specialization, the shortcomings of the traditional direct propulsion mode of diesel engines gradually appear. China has a vast territorial sea and rich marine resources. Exploitation of these resources requires a variety of excellent performance, special functions of the ship, at the same time the ship as the main body of the shipping industry. Its own performance will also have an impact on the development of the industry. Hydraulic transmission with large power and quality ratio, good overload security and other characteristics, hydraulic motor can be installed in the 360. rotary pods. Using hydraulic motor to drive the propeller, the podded hydraulic propulsion system is formed. The podded hydraulic propulsion system takes into account the advantages of hydraulic transmission and can realize vector propulsion at the same time. Become a new type of ship propulsion. In this paper, the hydraulic propulsion system is designed for a 2320t maritime official ship. According to the ship type parameters provided, the resistance of the ship is estimated by using the Thalo method. In the preliminary design of propeller, the optimal speed, pitch ratio and open water efficiency of propeller are calculated by MATLAB programming. In the system design, through calculation, the performance parameters of the key components of the system are determined, and the selection of the products of REXROTH company is carried out. Draw the schematic diagram of hydraulic propulsion system. Use the power bond graph theory to model the system and deduce the state equation of each sub-model of the system. LMS AMEsim software based on bond graph theory is used to simulate the system performance from pump control signal and pipeline layout. The influence of external factors on system performance is analyzed in several aspects, such as load.
