【摘要】 减摇鳍作为船舶的主要减摇装置，已经被使用了70多年，其优良的减摇效果已经得到公认。但它并非十全十美，仍然存在着许多需要改进的地方。目前使用的绝大多数减摇鳍都是鳍角控制系统，它通过鳍的转角来计算控制力矩。这样就存在一些不足之处，因为鳍上产生的升力和鳍角的对应关系主要从鳍的水动力试验得到。而鳍的水动力试验存在着很大的误差，特别是在动态条件下，鳍的水动力特性测试更困难，所以这种通过计算求得控制力矩的方法产生的鳍的升力无法很好地抵消波浪力矩，从而影响了减摇效果。如果我们能够直接测得鳍上产生的升力，就可以避开鳍角转化为升力时的诸多不确定因素。这就是升力控制减摇鳍系统的基本思想。 升力控制减摇鳍是一种全新的减摇鳍，它从控制原理上对传统的减摇鳍进行了改进，具有很多的优点。升力控制减摇鳍的研制，对于更好的发挥减摇鳍的作用，进一步提高减摇效果具有重要意义。 本论文首先对比鳍角控制减摇鳍系统，对升力控制减摇鳍系统组成进行了深入地研究，建立了升力控制减摇鳍系统的数学模型，比较得出升力控制减摇鳍能够从根本上解决鳍角控制减摇鳍通过估算鳍上产生的升力所带来的问题。其次，在回顾总结升力减摇鳍系统研究的基础上，构建和完善升力控制减摇鳍试验台的硬件实验装置；参考了鳍角控制减摇鳍系统的设计，完善并调试了升力控制减摇鳍实验装置的软件监控系统。最后，通过试验，验证了升力控制减摇鳍系统实验装置的各部分性能并取得了一些有益的试验资料和试验结论。试验研究结果证明，施力系统的力跟踪性能能够满足试验要求；而升力随动系统的跟踪能力距离试验要求还存在着很大的差距，还需要针对系统本身和升力测量信号进行深入的研究和分析。更多还原

【Abstract】 Fin stabilizer, which has been used more than seventy years, is the main equipment to stable the ship. But it is not so excellent that there are many problems to solve. Most of the fin stabilizers we use now are angle-control system, whose control torque is gotten by the calculation of fin angle. Because the relationship between the lift on the fin and the angle is gotten by the hydrodynamic experiment, which has great error, especially dynamic hydrodynamic experiment, the control torque gotten by the experiment can not counteract the wave torque well and the stabilization result is not perfect. If we could obtain the lift directly all the problems in angle transition will be avoided. That’s the principle of lift-control fin stabilizer.Lift-control fin stabilizer is a new kind of perfect stabilizer, whose control theory is improved on the basis of classical one. The research on lift-control fin stabilizer is so significant to improve stable effect and make the stabilizer work better.In this essay, firstly on contrast with angle-control fin stabilizer system, lift-control fin stabilizer system has thoroughly been studied, and the model of lift-control fin stabilizer system is built. By comparison, obtain that lift-control fin stabilizer can fundamentally solve the problem that estimates the lift of fin in angle-control fin stabilizer brings. Secondly, on the basis of reviewing and summing up the research on lift-control fin stabilizer, construct and consummate the hardware installation of the test platform of lift-control fin stabilizer; referred to the design of angle-control fin stabilizer, consummate and debug the software supervisory system of the test platform of lift-control fin stabilizer. At last, through the experiment, confirm the performance of each of the test platform of lift-control fin stabilizer, and obtain some beneficial experimental materials and experimental conclusions. The experimental study result proved that the strength track performance of the load-lift system can satisfy the experimental request; but the strength track performance of the lift servo system dissatisfies theexperimental request, and also needs thoroughly conduct the research and analysis on system itself and the lift survey signal.更多还原
