著陸沖擊
英文
landing shock-
Establishing an human spine dynamic model is an significan event to study spine injured biomechanics of pilot " s ejective injury, parachute opening, landing and study the endurance to impact loading on human spine. in this paper, the huston " s method of kane " s equations is developed so that it can be applied to the multibodysystem including translation between the bodyies. the dynamic model of human spine is provided basing on these theories, while the big movement of spine is considered. the deformation of vetebra is far smaller comparing with the intervetebra disc, so the spine is considered into multibodysystem including rigid bodies ( vetebra ) and the flexible bodies ( intervetebra disc ). the computer solution correspond with the results of the large scale human impact test. the rigid coefficient factors and the damping factor of intervetebra joints are obtained
人體脊柱動力學模型的建立對研究飛行員彈射救生、傘兵跳傘開傘、著陸等脊柱損傷的生物力學以及研究人體脊柱耐受沖擊載荷的極限問題都具有重要意義.首先發展了凱恩方程的休斯頓方法，使其可應用於變形體連接的多體系統，並以此理論為依據建立人體整椎脊柱沖擊動力學模型，此時考慮脊柱的大位移運動，每個椎骨的變形相對椎間盤的變形小得多，把脊柱看成由剛體（椎骨）和變形體（椎間盤）組成的多體系統.並以大型真人坐姿沖擊實驗結果進行了擬合，最後得到腰椎間關節剛度系數因子和阻尼系數因子He was alone when he set out last week on what was to be a three - hour flight, looking for a large flat area where he could try to set a new land speed record on the ground
他上個星期又一次單獨起飛，他當時的計劃是要飛行3個小時，尋找一片平地，沖擊最快著陸速度的世界記錄。The new china space center in aerospace city, a southwestern suburb of beijing, is home to a collection of pressure chambers, space - vehicle simulators, a centrifuge and a landing - impact tower, along with classrooms and medical facilities for astronauts
北京西南方郊區的航天城最新落成一座太空中心，擁有許多壓力室、太空模擬艙、離心機、著陸沖擊塔，還有給太空人的教室和醫療設施等等。How to precisely simulate the landing process of an aircraft and effectively absorb aircraft landing kinetic energy to attenuate the impact loads on aircraft is a problem facing the landing gear community
如何精確模擬飛機著陸過程起落架和機身的動態響應，並據此設計減小飛機著陸過程中的沖擊載荷的方案，一直是飛機起落架設計和分析中的重要課題。However, due to differences in the thinking style of the two law systems, the history background, the culture tradition, and so on, the trusts system which has strong common law trait is not in harmony with the traditional civil law system, and conflicts with the former law in a certain extent
但由於法系思維、歷史背景以及文化傳統等方面存在諸多不同，帶有濃厚英美法色彩的信託制度並不能很好地融入大陸法系固有的民法體系，並在一定程度上沖擊著原有的法律制度。During aircraft take - off and landing phases, the dynamic loads and vibrations caused by landing impact and the unevenness of runway will result in airframe fatigue, discomfort of passenger and the reduction of the pilot ' s ability to control the aircraft
在飛機起飛和著陸過程中，由著陸沖擊和跑道不平引起的沖擊載荷和振動，會造成飛機機體疲勞損傷、乘客不適及地面駕駛操縱能力的降低。因此，在設計飛機起落架緩沖器時，必須限制起落架傳遞給飛機的沖擊載荷。Internet began to land china and affected campus in universities with unprecedented speed in later 20th century
二十世紀末，網際網路開始登陸神州大地，並以前所未有的速度沖擊著大學校園。Thirdly, do theory analysis and parameters optimization. by modifying the parameters that make effect on the stiffness and the joint damping coefficient, confirm a set of parameters which can reduce the vibration and impulsion, meanwhile enhance the reliability and stability of the system. finally, design the experimental platform, and set up the testing system
再次，對著陸梯在外拉力作用下進行理論分析和參數調整，通過調整彈簧剛度、關節阻尼系數等參數，分析各主要參數對著陸梯釋放過程的影響，確定合理參數，在保證著陸梯順利釋放的基礎上，減小釋放過程中的沖擊和振動，增加系統的可靠性和平穩性。While landing ( ditching ), the aircraft will impact for several times ; take your brace position until the aircraft comes to a complete stop
"在飛機著陸（水）時，會有多次撞擊，保持您的防沖擊姿勢直到飛機完全停穩。It is proved by the analysis that, during the symmetric landing of that airplane, the impact load of the after main landing gear is the largest among those landing gears and the nose landing gear comprised of about 18 percent of the total impact load
分析表明:該樣機在對稱著陸過程中，後主起落架承受的地面載荷最大，前起落架輪胎僅承擔了全機18 %的沖擊載荷，載荷分佈較普通的前三點式起落架有明顯的改善。During the process of landing, an aircraft is exposed to a short - duration impulsive impact
