航天器運輸過程中誘發(fā)的動力學(xué)環(huán)境分析

Dynamics environment excitations during spacecraft transportatio

摘要: 文章綜合評述了航天器在公路,、鐵路,、船舶以及航空運輸過程中所誘發(fā)的動力學(xué)環(huán)境的原因和特點。對某型號在公路運輸和航空運輸過程中振動數(shù)據(jù)的統(tǒng)計分析結(jié)果表明：在公路運輸過程中,，路面不平和車輛的突然加速是誘發(fā)振動,、沖擊的主要來源；在航空運輸過程中,，飛機起飛,、降落以及飛行中的氣流擾動而引起的顫振是動力學(xué)環(huán)境的主要誘因。

Abstract: This paper reviews the characteristics of the dynamics environment while the spacecrafc is transported on road, railway, ship and airplane, respectively. Some data of the induced vibration of a spacecraf model in the road transportation and the airplane transportation are presented and analyzed statistically. The results show that the dynamics excitation of the road transportation is caused by the rolls and swells of the ground and the sudden speedup, and that of the airplane transportation is caused by the taking off or landing, and also by the flutter from the turbulence of surrounding flows.
