| 3. | Full scale ship power measuring of quot; fangcheng quot; trailing suction hopper dredger and operational sailing speed forecast after draghead transformation 号耙吸挖泥船实船功率测试及耙头改造后作业航速预报 |
| 4. | The energy dissipation efficiencies of four common loading systems for self - propelled trailing suction hopper dredgers were compared 试验结果表明各种装舱装置的优劣效果差距并不明显,仿新海龙型装舱装置效果略好。 |
| 5. | Improving the working character and the efficiency of trailing suction hopper dredgers will greatly increase the production , save power and bring more interests for dredging industry 改善耙吸式挖泥船的工作特性和工作效率将大大提高疏浚产量、节省能源,为疏浚工程创造更多的效益。 |
| 6. | The necessity of the yangtze estuary waterway administration bureau ' s purchasing of specialized trailing suction hopper dredger is analyzed , and suggestions on the way of building of the dredger are put forward 摘要对长江口航道管理局购买专用耙吸式挖泥船的必要性进行了分析,并对专用挖泥船建造方式提出了建议。 |
| 7. | Along with lime ' s moving the vessels and equipments which been built by the national investment , one older year by year , in particular , the expensive middling self - propelled trailing suction hopper dredgers 随着时间的推移,早先由国家投资建造的船舶机具,尤其是价值昂贵的中型自航耙吸挖泥船都逐渐老化陈旧,疏浚能力日益衰减。 |
| 8. | The results of the analysis of the investment wax and wane balance point prompt that the balance point of building 18000 - m3 self - propelled trailing suction hopper dredgers is higher and the anti - risk capacity is weaker 25年,还贷期小于8 26年。对投资的盈亏平衡进行分折结果表明,建造舱容is000m ’自航耙吸挖泥船盈亏平衡点较高,为74 |
| 9. | So , it is better to select building the large self - propelled trailing suction hopper dredgers abroad . however , the modern dredger is not only a technique a alone together but property article , especially large self - propelled trailing suction hopper dredger 然而,现代疏浚船舶尤其是大型自航耙吸挖泥船不仅是一种技术密集型的商品,更是一种资产密集型的商品,耗资之巨非上海航道局的财力所能承受。 |
| 10. | This dissertation firstly discusses the basic structure of trailing suction hopper dredgers , then establishes the mathematical model of dynamic process of trailing suction hopper dredgers and the model of compensator of wind and wave , develops a set of real time simulation software using oop visual c + + , mfc , delphi and activex component technology , and simulates the different dynamic characters for different working situations 本文从讨论耙吸式挖泥船基本结构和基本工作过程着手,建立了耙吸式挖泥船疏浚系统的数学模型,采用面向对象的visualc + + 、 mfc图形函数、 delphi和activex控件技术,开发了一套实时仿真软件,仿真了不同疏浚工况下的动态特性。 |
