滑行艇波浪中运动性能试验研究

Experimental investigation of seakeeping performance on a planning boat

为了探究自主开发的滑行艇耐波性能,在拖曳水池中进行该滑行艇模型不同航速下的静水阻力试验、不同航速下变波长顶浪规则波试验与对应不同海况的不规则波试验,试验过程中记录阻力值和纵向运动响应值。对试验结果处理分析后发现:在排水体积傅氏数Fr=3.713时,滑行艇在5倍于船长的波长附近具有强烈的运动响应,出现了抨击和出水现象;与传统深V滑行艇相比,短波中该滑行艇具有更小的运动响应,滑行艇阻力增值较深V滑行艇有所减小;垂荡响应与航速与波高具有较好的线性关系,纵摇响应航速与波高具有弱非线性。

In order to explore the seakeworthiness of a new type of planing boat independently developed, the hydrostatic resistance test of the model at different speed, the regular wave breaking test at different speed and the irregular wave test corresponding to different sea conditions were carried out in the towing tank, and the resistance value and longitudinal motion response value were recorded during the test.After processing and analyzing the test results, it is found that the sliding boat has a strong motion response near the wavelength of 5 times as long as the captain when the volume Fourier number Fr=3.713.Compared with the traditional deep V coasting boat, the short wave coasting boat has a smaller motion response, and the resistance increment of the coasting boat is smaller than that of the deep V coasting boat.There is a good linear relationship between heave response and velocity and wave height.
