减摇陀螺在船舶上的应用分析

Sea-keeping Analysis of Gyrostabilizer on Ship

针对某沿海小型科考船摇摆运动过大的问题,对其加装减摇陀螺。为测试减摇陀螺的减摇性能,使用差分GPS数据采集仪对该系统进行实海测试分析。测量过程中基于不同船速和减摇陀螺是否运转,采用了4种工况。测试结果表明:该减摇陀螺在零航速时纵摇减摇率为26.24%,横摇减摇率为48.82%,航速4 kn时纵摇减摇率为11.70%,横摇减摇率为69.27%,该减摇陀螺具有良好的减摇性能。

In order to solve the over-rocking problem of a small coastal research vessel, it is installed a gyrostabilizer. Using the differential GPS data acquisition instrument to test the stabilization of the gyroscope in the sea. During the testing, there are four conditions based on different speeds of ship and whether turning on the gyrostabilizer. And the results indicate that at zero speed, the gyrostabilizer can reduce 25.51 percent of pitching and 44.63 percent of rolling, and at 4 knots speed, it can reduce 19.29 percent of pitching and 34.12 percent of rolling, which prove the good stabilization performance of the gyrostabilizer.
