1、深水重力式组舍同箱水动力特性的试验研究Y75613,7.论文摘要《深水重力式组台网箱水动力特性的试验研究》为辽宁省教育厅攻关计划基金项目。试验工作主要在大连理工大学海岸和近海工程国家重点实验室进行。试验工作主要包括重力网箱模型的制作,单纯流、单纯波浪、波流混合作用下的组合式网箱试验。试验目的有两个,第一是通过试验室物理模型试验,测出各种海况条件下网箱的锚绳受力,第二是通过试验室物理模型试验,测出网箱的浮架运动。论文也从两方面进行了分析,一方面分析了锚绳受力,研究锚绳受力的主要影响因素以及与各因素的关系,从受力角度比较各种组台式网箱的差异,优化组
2、合式网箱结构;另一方面分析了浮架运动,研究浮架运动的主要影响因素以及与各因素的关系,从运动角度比较各种组合式网箱的差异,优化组合式网箱结构。试验取得了以下主要成果:1、据相似原理及试验条件,由原型网箱制作成模型网箱。2、分析了五种组合式网箱的各道锚绳的最大受力,得到了锚绳受力与波浪要素和流速的初步关系:3、分析了组合式网箱的浮架运动,得到了浮架运动轨迹图和运动幅度。4、从受力和运动两个方面分析,优化组合式网箱。关键词:组合式网箱;模型试验:水动力特性;波浪;水流深水重力式组合网箱水动力特性的试验研究ABSTRACT3、drodynamicbehaviorsofcombinatorialGravitycages>wassponsoredbyprogramoftheOfficeofEducationofLiaoningProvinceFund.ThisexperimentwascarriedoutintheStateKeyLaboratoryofCoastalandOffshoreEngineeringofDalianUniversityofTechnology.Thisexperimentprocessincludedthemakingofmodelsande4、xperimentofcombinatorialGravitycagesunderpurecurrentsandexperimentofcombinatorialGravitycagesunderpurewavesandexperimentofcombinatorialGravitycagesunderwavescombinedwi也currents.ThereweretwoailnSinthisexperiment.Bythephysicalmodeltests,firstaimwastocalculatetheforcesunderwave5、sandcurrents;secondwastocalculatethemotionofcageunderwavesandcurrents.ThearticleWasanalyzedintwoaspects.Thearticleanalyzedtheforcesunderwavesandcurrents,andanalyzedthekeyfactorsofforcemechanismandtherelationshipofthefactorstOoptimizetheconstructionofcombinatorialGravitycages6、.Thearticleanalyzedthemotionofcageunderwavesandcurrents,andanalyzedthekeyfactorsofmotionofcageandtherelationshipofthefactorstooptimizetheconstructionofcombinatorialGravitycages.Theexpectedresultswereachievedandlistedasfollows:1.Basedonsimilitudecriterion,themodelsofcombinato7、rialGravitycagesweremadefromtheprototype.2.ThearticleanalyzedthemaximalforcesoncombinatorialGravitycagesunderdifferentconditions,andgottherelationshipofthemaximalforcesandthewavefactors,andgottherelationshipofthemaximalforcesandthecurrent.3.Thearticleanalyzedmotionofthefloat8、ingsystemofcombinatorialGravitycages.andgotthetrackofthefloatingsystem,andg
