摘要
本文根据船舶水弹性统一理论,研究了波浪引起的船体对称振动,编制了计算程序,并作了实例计算和浅吃水肥大船分段弹性龙骨模型试验,两者结果比较基本相符。本文还用切片理论计算了浅吃水肥大船的波浪诱导弯矩和切力,表明该理论预报船体的动力响应误差较大,在船舶设计中宜采用新的船舶水弹性理论。
The symmetric vibration of hull induced by waves has been studied,using the theory of hydroelasticity, and a computer program has also been developed. The calculation on the response of a shallow draft fullform ship and the experiments of a segmented elastic keel model were carried out. The comparison between the calculation and model tests shows that the test results are in accordance with the theoretical prediction.In addition, the authors also computed the wave bending moments and shear forces for the same ship by the strip theory. It is shown that the results computed by the strip theory fail to predict the dynamic response of ship hull accurately. Therefore, it is better to use the new hydroelasticity theory in ship design.
