| 摘 要： | 文章综合评述了航天器在公路、铁路、船舶以及航空运输过程中所诱发的动力学环境的原因和特点。对某型号在公路运输和航空运输过程中振动数据的统计分析结果表明：在公路运输过程中,路面不平和车辆的突然加速是诱发振动、冲击的主要来源;在航空运输过程中,飞机起飞、降落以及飞行中的气流扰动而引起的颤振是动力学环境的主要诱因。

| Abstract: | This paper reviews the characteristics of the dynamics environment while the spacecraft is transported on road,railway,ship and airplane,respectively.Some data of the induced vibration of a spacecraft 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. |
