船舶在波浪中大幅度运动和载荷时域预报

切片理论具有其它方法无法比拟的优点,目前已成为船舶在波浪上运动和载荷计算和预报的一种常规的实用手段。本文基于扩展的切片理论,计入船体运动时湿表面的变化及其对船体流体动力性能的影响,在时域内计算了船舶在波浪中的运动和载荷,本文的研究对船舶设计阶段的耐波性能评估具有工程实用价值。

Ships in wave large scale movement and load time domain forecast

The slice theory has the merit which the other means are unable to compare, at present has become the ships in the wave the movement and the load computation and the forecast one convention practical method. This article based on the expansion slice theory, includes when the hull movement the wet superficial change and to the hull hydrodynamical performance influence, has calculated the ships in wave movement and the load in the time domain, this article research to the hull design stage neper performance appraised has the project practical value.
