摘要
为解决船舶在向大型化、高速化方向发展时船舶主机设计困难,机舱布置不合理以及机动性能差等问题,提出船舶综合液压推进,建立该系统的数学仿真模型,并通过试验台测试数据对该模型进行验证.针对该推进系统的特点,提出船舶综合液压推进恒功率与变功率联合控制方法(CVCC).基于配合元件的特性以及仿真模型,分别通过理论分析以及仿真试验对CVCC控制方法进行分析研究,两者相互印证,同时给出系统主要参数变化情况.结果表明,应用该控制方法可保证主机持续运行在最佳工况,使主机功率得以充分利用,克服了柴油机直接推进系统中,主机在轻载以及重载工况下无法发出设计功率的缺点.
With increases in volume and speed of ships, the design of their main engines has become more complex. Also, cabin arrangements and ship maneuverability have suffered. To solve these problems, a new ship propulsion method, called integrated hydraulic propulsion （IHP）, is proposed. A dynamic mathematical model of an IHP ship was developed. The model was verified with data from a test platform. The features of this kind of propeller in an IHP ship allow the introduction of a control method combining constant power and variable power. Theoretical analysis and simulations were conducted to test the model. Typical variations of major parameters of the system are given. Results showed that the new control method can allow diesel engines on an IHP ship to operate under ideal working conditions, making full use of their power. But for direct propulsion （DP） ships, an engine cannot generate its full rated power when the DP ship is either heavily or lightly loaded.
