摘要
船舶减摇鳍在零航速时进行减摇是一种全新的理论。为了研究船舶零航速减摇鳍的升力特性,以Weis-Fogh理论为基础,建立了零航速减摇鳍升力模型,并针对哈尔滨工程大学研制的NJ5型减摇鳍对二维升力模型,在Matlab环境下进行了各种运动规律的仿真实验,结果证明,Weis-Fogh机构减摇鳍在零速流场中能够瞬间产生很大的升力,为以后进一步进行水动力试验以及控制规律的研究打下了基础。
The method that the fin stabilizer is used for anti-rolling ship at zero forward speed is a new one in theory. In order to study the characters of lift generation of fin stabilizer at zero speed, the model of lift generation of fin stabilizer is established, based on the theory of Weis-Fogh mechanism, and for the NJ5 fin stabilizer of Harbin Engineering University developed, the 9 dimensional lift generation model is studied by simulation at Matlab environment. The result shows that the Weis-Fogh fin stabilizer can produce huge lift, which will lay foundations for the practical fluid mechanical experiment and the research on controlled strategies.
