Abstract

In view of the 360° continuous rotation characteristic of the microwave imager barrel, a flip-type locking and release mechanism applicable to aerospace working conditions is designed in this paper, which realizes rigid locking of the barrel during the launching phase and reliable unlocking after orbital insertion. Firstly, the overall structural scheme of the locking and release mechanism is completed. Based on the multi-body dynamics theory, ADAMS software is adopted to establish the dynamic simulation model, and the kinematic characteristics and mechanical properties of the mechanism are verified by simulation. Secondly, relying on the parameter optimization module of the software, optimization design is carried out for core parameters such as locking rod length and compression spring preload, and the optimal structural matching parameters are determined. Finally, a physical prototype is fabricated, and a ground test platform is built to complete the performance test of the mechanism through multiple ground tests. The test results show that the designed locking and release mechanism possesses reasonable structure and reliable performance, which can satisfy the application requirements of launching locking and on-orbit unlocking for the microwave imager barrel, and provide important technical support for subsequent model development.

Mechanism and simulation analysis of preload relaxation in guide-rail bolts

Accurate bolt preloading is a critical procedure for ensuring the long-term high-precision assembly, reliable load-bearing capacity, and dynamic stability of high-end machine tools. In the assembly of machine tool guide rails, bolt relaxation directly degrades the straightness of linear-axis motion and is therefore a k...
