STUDY ON ATTITUDE DYNAMICS OF A LIQUID-FILLED SPACECRAFT WITH ELASTIC APPENDAGES
摘要
Abstract
In this paper attitude dynamics of liquid-filled spacecraft with elasticappendages is studied. Motional equations of liquid, motional equationsof system and motional equations of particle of elastic plates areobtained by using the theorem of angular momentum, the conservation lawof angular momentum and Newton's motional law. When elastic platesdeploy at uniform velocity of plates motional equations of plates arealternated. Using Runge-Kutta method, the plate's amplitudes ofvibration are obtained. Using motional equations of system,the attitudeangular velocities of spacecraft are obtained.关键词
