万吨级船舶气囊下水研究成果

Fhe Application of Air Bag in Launching lO000-ton-class Vessel

气裳下水技术是我国具有自主知识产权的一项高新技术。本文基于气囊下水存在的一系列技术问题，通过气囊压缩试验、实船下水过程测试等方法的不断探索、研究，对大型船舶下水用气囊的结构及性能参数要求、船台坡道参数、牵引力计算以及下水计算等方面进行了深入的研究，总结出了一套完整的计算方法。研究结果已在7万吨和8．2万吨等船舶下水实践过程中得到了充分的认证，从而为大型船舶的下水提供了一套技术理论支持。

Utilizing air bags to launch ships is a technology with independent intellectual property rights. Based on air bag compression test and ship lannching test,a series of technical solutions have been explored.Taking into account the requirements of both structure and performance parameters of air bag, the launch ramp＇s parameters, the traction while launching and launching process analysis methods, etc, a comprehensive calculation method is summed up in this paper, The research results have been proved in ship launching practices from 70000dwt to 82000dwt, so as to create a set of technic and theory basis for application of air bag in launching lO000-ton-class vessels.
