Thermal analysis of control moment gyroscopes based on the thermal network method 基于热网络法的控制力矩陀螺仪热分析
IF 3.4 2区 物理与天体物理 Q1 ENGINEERING, AEROSPACE

Control moment gyroscopes serving as high-power attitude actuators for large spacecraft require sustained lubrication performance of their high-speed bearings to ensure long-term operation. A critical challenge arises from the temperature-dependent release rate of lubricant stored in oil reservoirs, combined with structural constraints that impede direct temperature measurement at key bearing nodes. To address this issue, this study develops a thermal network modeling methodology for control moment gyroscopes that enables comprehensive and precise temperature estimation across all critical components. Experimental validation via thermal equilibrium tests demonstrates strong agreement between the measured and simulated temperatures (with an error coefficient of less than 12 %). The verified thermal network model provides an effective theoretical framework for the on-orbit thermal management and failure early warning of control moment gyroscopes, thereby enhancing operational reliability and extending lifespan. This methodology offers significant value for precision thermal control in advanced aerospace instrumentation systems.
控制力矩陀螺仪作为大型航天器的大功率姿态执行器，要求其高速轴承具有持续的润滑性能，以保证其长期运行。一个关键的挑战来自于储存在油藏中的润滑油的温度依赖性释放速率，以及阻碍关键轴承节点直接测量温度的结构限制。为了解决这个问题，本研究开发了一种用于控制力矩陀螺仪的热网络建模方法，该方法可以对所有关键部件进行全面而精确的温度估计。通过热平衡测试进行的实验验证表明，测量温度和模拟温度之间的一致性很强（误差系数小于12%）。验证的热网络模型为控制力矩陀螺仪在轨热管理和故障预警提供了有效的理论框架，从而提高了运行可靠性，延长了使用寿命。该方法对先进航天仪器系统的精密热控制具有重要价值。
