船舶NAPA软件学习笔记

NAPA软件使用笔记摘要潮流发电船这一较为特殊的船型，因其使用功能不同于常规的货船，带来了许多特殊的工况，需要计算研究。本文运用NAPA（theNavalArchitecturalPackage）软件，进行发电船建模，静水力计算，舱容计算，完整稳性计算，破舱稳性计算，熟悉稳性计算的过程和相关衡准的要求，回顾船舶静力学、船舶原理等课程的知识。本论文涉及如下工作：学习NAPA软件中的稳性计算的模块；在NAPA软件中建立船型模型包括生成船体表面和完成内部分舱；静水力计算，舱容计算，和静水力曲线图的绘制；空船重量重心和重量分布的估算；基于规范要求工况的完整稳性和破舱稳性计算。本论文的完成，为进一步深入研究NAPA软件对水面式海上平台稳性校核打下基础。关键词：NAPA；发电船；静水力；完整稳性；破舱稳性NAPA软件使用笔记ABSTRACTTidalgeneratorstationisaspecialshipmodel,Differentpurposeincomparisonwithtraditionalcargoshipcomeswithspecialworking-conditiontostudywith.Inthispaper,anattempthasbeengiventocreatethehullmodelbasedonwhichtheHydrostaticdata,Capacitydata,IntactstabilityandDamagestabilitywillbecalculatedaccordinglybyusingNAPAsoftware.FurthergrasptheIMOcriteriapertainingtostabilitywhereasdeepentheunderstandingofthecourseofHydrostaticsandShipdesignprinciple.Themainworkinvolvinginthisthesiscontains:StudyonNAPA‟smodulesinrelationtostabilitycalculation.Workongeometricdefinitionandinternalsubdivision.Calculationofhydrostaticdataforgivenfloatingpositions,outputthecapacitiesofrooms.Inputthelightweighttable,estimatesCGandmassdistribution.Theintactanddamagestabilityanalysisincriteria.Uponthisthesis,thefundamentalworkwouldbeexpectedtothefurtherinvestigationonstabilityoftidalgeneratorstationinNAPA.Keywords：NAPA;Tidalgeneratorstation;Hydrostatic;IntactandDamagestabilityNAPA软件使用笔记目录第1章绪论.......................................................................................................11.1论文背景..................................................................................................11.2国内外潮流能利用发展情况..................................................................21.3论文主要工作..........................................................................................7第2章NAPA软件工作原理.......................................................................82.1软件工作原理..........................................................................................82.2本章小结................................................................................................11第3章船体模型的建立..............................................................................123.1操作界面................................................................................................123.1.1NAPA软件..................................................................................123.1.2建立项目.....................................................................................133.2几何建模................................................................................................143.2.1船体表面曲线定义.....................................................................153.2.2三维船体表面生成.....................................................................183.2.3船体舱室划分.............................................................................193.2.4总布置设置.................................................................................213.3船舶型线建立........................................................................................213.4本章小结................................................................................................22第4章静水力计算.......................................................................................234.1项目参数设定........................................................................................234.2静水力数值计算....................................................................................244.3舱容计算................................................................................................264.3.1舱容定义.....................................................................................26NAPA软件使用笔记4.3.2舱容数值输出.............................................................................264.4本章小结................................................................................................31第5章稳性计算............................................................................................325.1装载工况设定........................................................................................325.1.1LD模块功能................................................................................325.1.2空船重量.....................................................................................325.1.3装载定义.....................................................................................345.1.4自由液面修正.............................................................................365.1.5强度限制曲线.............................................................................365.1.6OPENING....................................................................................365.1.7输出.............................................................................................375.2稳性衡准................................................................................................375.2.1完整稳性和破损稳性衡准联系.................................................375.2.2主要衡准.....................................................................................385.2.3船体稳性模型.............................................................................385.2.4自定义稳性衡准.
