摘要
在"蛟龙"号载人潜水器5 000米级海试中,D44潜次首次实现了全程无动力上浮下潜运动,为改进载人潜器无动力上浮下潜运动模型提供了宝贵的数据。文章对D44潜次的数据进行了分析,在此基础上引入可变体积收缩率的概念来改进潜器无动力上浮下潜运动模型,开发出了更为可靠的"蛟龙"号载人潜水器的无动力潜浮运动分析系统,为7 000米级海试以及今后的应用提供可靠的手段。
In this 5 000m depth class sea trials test of the JIAOLONG deep manned submersible,dive No.44 has realized the fully unpowered diving and floating condition and this set of test data provide a valuable source for model improvement.In this paper,this set of test data is analysed in detail and the previous analytical model is improved through the introduction of a variable volume compressed rate for the deep manned submersible during the whole process of diving and floating.A computer software is developed for the prediction of the unpowered diving and floating movement.This could lay a good foundation for the 7 000m sea trials planned in 2012 and for the future applications.
