摘要
为分析海洋一号(HY-1)卫星水色扫描仪(水色仪)在轨发生的转动机构与卫星间耦合振动对步进电机工作状态的影响,根据建立的步进电机+角速度振动环境、步进电机+卫星+太阳帆板两种不同模式的电机运动状态模型,在不同设计参数条件下进行了仿真。结果表明:步进电机会因与卫星耦合振动造成工作状态变差,影响步进电机在轨工作状态的主要因素是卫星结构基频。
To analyze the influence of the coupled vibration between the rotation mechanism and the satellite on the working statement of the on-board stepping motor in ocean color and temperature scanner for HY-1 ocean satellite,the numerical simulations under various design parameters were done according to the two dynamic models of stepping motor + velocity vibration environment and step motor + satellite + solar panel established in this paper.The results showed that the working statement of the on-board stepping ...
