航天器动力学发展概况

DEVELOPMENT GENERALIZATION OF SPACECRAFT DYNAMICS

分析了现代航天器动力学的复杂性 ,将现代航天器动力学的发展概括为以下几个方面 :1)局部动力学的研究受到重视 ;2 )部件级子系统动力学研究的深入 ;3)耦合动力学研究进入非线性阶段 ;4)整体航天器动力学模型精化与一体化仿真 ;5 )航天器与航天器之间相对运动动力学研究方兴未艾等。

The complexity of modern spacecraft dynamics was discussed. The development of modern spacecraft dynamics was generalized as follows: 1)Attention to the local dynamics was paid more and more;2)The dynamics of appendage subsystem was studied deeply;3)The study of coupling dynamics was focused on nonlinearity;4)The dynamical model and its simulations of the whole spacecraft became more and more accurate;5)The study of relative motion dynamics between spacecrafts was in the ascendant.Some comments and discussions were made.
