An HCPS-Based Inspection Method for Bearing Assembly Quality of Coarse Pointing Mechanism

The laser communication terminal (LCT) is a vital component of satellite communication networks, where the accuracy of the laser pointing plays a significant role in ensuring high-quality communication. The Coarse Pointing Mechanism (CPM) is a crucial mechanical component used in LCT to maintain the laser's pointing accuracy. It is imperative to adjust the CPM's attitude in real-time during satellite movement and maintain its high rotational stability, which primarily depends on the bearing system. This paper proposes a human-machine collaborative method for the quality inspection of the CPM bearing assembly to ensure the precision. The process of inspecting the CPM bearing assembly quality is described in detail, focusing on the essential operations that humans need to perform and the data that they should record. A CPM bearing assembly quality inspection method based on the Human-Cyber-Physical System (HCPS) is proposed, and its operating mechanism is explained. The shaft wobbling after bearing assembly is taken as an example to illustrate the effectiveness of the method in this paper.
