ship-design data 中文意思是什麼
ship-design data
解釋
船舶設計數據-
Especially for ship and ocean - platform structure, there are a lot of stochastic factors affecting their design, for example, wave, tidewater and wind which act on the ship surface are indeterminate ; material data and dimension data provided may be not completely consistent with that of real structure ; some hypothesis, for convenience and simplification, make the calculation model is not the same as the real structure
特別對船舶與海洋平臺等結構，影響結構設計的隨機因素很多，例如作用在船舶上的波浪、潮水和風荷載都是不確定的；結構中用的材料物理性能數據可能與提供的有所差異；名義尺寸也可能與實際結構不完全一致；計算中引進的一些假設，也會使計算模式與實際情況有所偏離等等。 -
A number of statistical and analytical works have been done by the institutions such as thethird shipping affair engineering and relonnissanle design institue of ministry of communications, hohai university, yangize valley water hudroprower planning and institule, nanjing hydraulic research institute and so on [ 25 - 30 ]. in 1993, the correlation analyses based on the data from the short - term situ - observation at near sea - route of the yangtse river estuary and the ship - stations were carried out to deduce the wave factors used in the engineering design
交通部第三航務工程堪察設計院、河海大學、長江流域水利規劃設計院、南京水利科學研究院等單位曾作過不少統計和分析工作[ 25 - 30 ] ，在九十年代前期，人們曾根據長江口深水航道或附近短期實測資料與引水船站進行過相關分析，進而推算出設計波要素。 -
What the article discusses is to design a computer plotting system to solve the problems how to promptly and precisely study out the above mentioned location and plotting problems. considering the affects of all kinds of factors and leaving enough room, to scan the safety course in all directions, make forecast about the relative position of the ship and typhoon, the tendency of their movements, render a vital group of data and a direct diagram which the captain cares about, help the users to make the scientific and resonable decisions, to take correct and effective measures to keep away from and withstand typhoon early and resolutely, for all the practical problems in decision - making to keep away from typhoon
本文所討論的就是為迅速和較為精確地解決以上點繪和相對運動標繪的問題，在考慮了各種因素的影響並留有充分餘地的情況下，在全方位范圍內搜索安全航向，對本船與臺風的相對位置以及兩者之間的動態發展態勢作出預報，並給出船長最關心的、對其作出避臺決策至關重要的一組數據和直觀圖形，幫助使用者及早制訂科學合理的避抗預案，及時果斷地採取正確有效的避抗措施，解決避臺決策的實際問題而設計的一個計算機標繪系統。 -
Secondly, a ship undocking process environmental forces testing plan is made by using the orthogonal design theory. measuring the environmental forces with different wind, wave and current combination from 0 ? to 90 ? and analyzing and processing the data are finished by using the analysis of variance method. comparing the experimental results with the results calculated using the ocimf method, the reliability of using the ocimf method is testified
二、利用正交設計方法，制定了船舶出塢過程環境載荷測量方案，完成了船舶在出塢過程中從90到0過程中在不同風、浪、流組合下的環境外力測試和分析處理，利用級差分析方法，重點分析了風、浪、流以及方向對船舶出塢的影響程度大小，並把試驗結果和ocimf方法計算結果作了比較分析，驗證了ocimf方法計算結果的可靠性。 -
The thesis analyzes in depth the present modes and methods of ship design, and studies parallel engineering. it proposes a ship design integration method based on pdm ( product data management system ), reference to the experiences in aeronautical and aerospace industries in home and abroad
本文深入地分析了目前船舶設計的模式與方法，並對并行工程進行了研究，參考國際國內航空、航天的經驗，提出了以pdm （產品數據管理系統）為基本框架的船舶設計集成方法。 -
Chapter 4 explains the design principle of the advanced navigation base on the ship ' s apparatus data, and accomplish the function in ecdis
第4章提出基於船舶導航儀器數據最優航法的設計原理，並將此最優航法嵌入電子海圖顯示與信息中，使之成為該系統的一個功能。 -
With the knowledge of mathematical fairing and fairing procedure, we divide and classify ship data first ; then we design the database, give the tables " structure ; after the analyzing and designing of the system, we develop " ship lofting cad / cam system " with visual c + + using odbc technology. the interface of the system is friendly to users
在對船體型線光順演算法和光順過程的充分研究的基礎上，我們首先對船體數據進行分類整理；然後進行數據庫設計，給出各種表結構；最後對系統功能進行分析設計，以visualc + +為開發工具，應用微軟的開放數據庫互連技術實現了「船體放樣cad cam系統」 。 -
This paper studies agent - based ship product collaborative design system on internet. the main contents in this paper are 1. the exchange of ship data is necessary for the ship collaborative design
在大范圍內實現船舶信息的共享、數據互操作和多個設計者的協同工作是縮短船舶設計周期，提高勞動生產率的重要手段。
