[0128] Task description: Reliability issues of dynamic cascade coupling of dual-axis drive mechanism
[0129] The dual-axis driving mechanism of satellite antenna is a typical electromechanical system in space agencies, and its reliability level is directly related to the safety of satellite antenna and the reliability of task completion. The dual-axis drive mechanism is the core component of the dual-axis movement of the antenna, including the horizontal axis drive assembly and the vertical axis drive assembly, and the two drive assemblies are completely consistent.
[0130] In the "Dynamic Cascade Coupling Reliability" problem of the dual-axis drive mechanism: the dynamic characteristics (torque and speed) of each component, subsystem and system, and the clearance of the kinematic pair change with time; the system response (displacement and angle of the antenna) is determined by The composition of the dynamic response of internal components (input shaft, rigid-flex wheel, ou...
