摘要
在建立了系统动力学模型的基础上,运用数值优化方法对减摇装置的参数进行了优化设计,得到了减摇装置的最佳频率和最佳阻尼;分析了减摇装置有无时系统的传递函数特性,仿真计算了减摇装置有无时船体对初始横摇角的响应及对外部激振的响应。结果表明,设计的减摇装置对船体的横向摇动有明显的减摇效果。
On the basis of setting up the dynamic model of ship with anti-rolling system, the numerical optimal method is used to carry out the optimal design of the parameters of anti rolling system, the optimal frequency and damping ratios of the system are then obtained. The frequency response characteristics is analyzed and compared for cases with and without the anti-rolling system. Also, the simulation calculations of the responses to initial condition and random rolling torque are carried out for the both cases. The results show that the designed anti-rolling system has obvious anti-rolling effectiveness.
