双体船在突风中摇摆运动的试验研究和理论计算

Experimental and theoretical researches on the rolling motion of the catamaran in gust

采用试验研究与理论计算相结合的方法研究了一条双体船在突风中的安全性 ,阐述了突风试验的方法和设备 ,并用时域的方法进行了该船横摇运动的理论计算 ,研究了该船的最大横倾角及其发生的时间 。

To assess the safety of a catamaran in the gust, experiments are carried out com bined with calculations. This paper describes the experimental method and equipm ents, and the method to compute the oscillation in time domain. Comparison and a nalysis are made between the test results and numerical ones, especially on the maximum rolling angle and its happening time.
