With the fea software ansys and shell element which has high - precision , this dissertation optimize the size and thickness of skeleton section and seek steel pipe which still have strength and stiffness surplus under static state working condition : sinkage of 240mm of rear wheel . it ' s fully loaded in the state of static bending and torsion . after that , amelioration is achieved for even strength design 本課題運用ansys有限元分析軟件，并且使用精度較高的shell殼單元作為建模單元，在靜態條件下，通過對左右后輪下沉240mm的彎扭聯合工況的模擬分析，尋找出骨架中存在強度和剛度富裕的構件，使之達到輕量化改進的目的。
Now some universities and institutes of china have made some samples of the lunar rovers and theirs wheels , but until now the wheel ’ s mechanical performance is seldom researched and tested . this paper will analyze the mechanical performance of the wheel and design a test - bed to test the performance of the lunar rover ’ s wheel . firstly , the mechanical characters of the soil are separated to press - sinkage character and shear character based on bekker ’ s theory , and common press - sinkage and shear models are introduced and the theory of lankine passive earth pressure is also introduced 根據bekker半經驗法的基本思想,將土壤的力學特性分解為水平方向的剪切特性和豎直方向的承壓特性,闡述了地面力學中常見的土壤的承壓、剪切等力學模型,并引入了朗肯被動土壓力理論,為建立車輪在松軟土壤中前進和轉向的力學模型奠定了基礎,同時進行了實驗土壤的剪切實驗,測量了土壤的內聚力和內摩擦角等參數。
The content of the study as follow : 1 to choice the ship form , mainly ship ' s overall size ; draft , according to design of shanghai deep - water port and development of container ; 2 . to deside the date of width ; depth ; path ; tract and sinkage through simulator tests ; 3 . to replenish and modify some date for channel design to very large container vessels in “ design code of general layout for sea port “ 4 . to study ship ' s turning area ; ship ' s stop distance the new and special content of the study as follow : 1 . statistics of path at the channel given by difference operators with the affections certain wind . currents . seas and other influences shows the path really needed under certain condition 并可在各類航道和水域的通航安全評估及操船方法，航跡帶寬度，航道寬度，航跡帶分布，船舶各種航行狀態時的下沉量研究中應用。本課題研究的內容： ( 1 )根據洋山深水港設計規劃和集裝箱船舶的發展趨勢，通過研究、分析、比較，選擇最合適的船型，尤其是船舶主尺度和船舶吃水。 ( 2 )在大量模擬研究情況下，得出進港航道所需的航道寬度和深度。
Simulator tests indicates the speed ; wave ; angle between ship and wave are main factors of the sinkage . difference factors given difference sinkage with simulator tests . 3 . the date of width ; depth are two important factors of channel design , the relationship between width to depth is speed （ 3 ）航道寬度和航道深度的關系，聯結這二者關系是航速，航道寬度和航道深度是決定航道參數的二個重要因素，并相互存在著一定的關系。
The other effect brings about by coat on a large scale is discussed preliminary which including increasing the “ hot island effect “ of cities ; increasing the hydrous of the roads after rain and increasing the sinkage of ground surface in the city 同時初步探討用水泥以及瀝青大規模地覆蓋土壤所造成的其他影響，這些影響包括加重了城市的“熱島效應” 、加重了城市由于雨后道路積水所導致的交通堵塞、加重了城市地面的沉降。
