摘要
依据相似理论,对船舶滑道下水这一复杂力学过程进行了力学分析并应用水力模拟试验的手段进行了探讨性研究,特别是就结构复杂的船架所受的水流绕流阻力的模拟做出实质性的探究。文中针对船舶滑道下水过程水力模拟试验研究建立一套指标以判定相似模拟试验是否相似。还就用何因素来判断船体和船架下水过程中的稳定性,提出了自己的看法。
Based on the similarity theory, mechanical analysis of the launching of ship＇s slipway is carried out by means of hydraulic simulation experiment, esp. simulation of the circumfluence resistance acted on ship frame which is of complicated structure. A set of indices for the judgment of the similarity of simulation experiment are established in light of hydraulic simulation experimental research on the launching of ship＇s slipway, and views on factors for judging the stability of ship body and ship frame during launching are put forward.
