## TEACHING RESEARCH AND STUDY FOR SPACECRAFT RELATIVE MOTION DYNAMICS

• 摘要: 航天器相对运动动力学是空间维护原理课程的核心,主要内容是目标轨道坐标系中两个航天器的相对运动规律,太空中的相对运动规律与地面的相对运动规律在直觉上是相悖的,对学员的理解能力提出了较高挑战,课程组提出了演示法、交互法和实验法有机结合的体系化教学方法,通过将隐含的运动关系、相对运动方程经过变换转化为显式的运动方程,将静态的公式转化为动态的案例运用,将抽象的相对运动规律转换为直观的图像、动画演示。实践表明,该教学方法可显著提高学员学习的积极性和动手实践能力,有效提高教学质量。

Abstract: Spacecraft relative motion dynamics is core content of space service principles and it focuses on two spacecraft relative motion laws based on target orbit coordinate. The relative motion laws in space are contradictory to the relative motion laws on the ground, which pose critical challenge to students' spatial imagination. The teaching team proposed a systematic teaching technique which includes illustration method, interaction method and experimental method. The implicit relative motion model is transferred into explicit expression through formula translation. The statical formula is demonstrated by case application and the abstract relative motion law is represented by vivid pictures and dynamic animation, etc. The practice indicates that the proposed method contributes to student learning enthusiasm and the teaching quality improvement significantly.
