摘要：
With increasing demand for driving torque of large antenna deployment in spacecraft, impact load control problem when antenna is unfolded in place has gradually attracted attentions of engineering community. Here, a rotating damper with large stroke and large damping was introduced for deployment mechanism of spacecraft, it could effectively suppress impact load during deployment mechanism deploying. Firstly, the working principle of this rotating damper was briefly introduced, its dynamic model was established to analyze its damping characteristics. Secondly, adopting the software MSC. ADAMS, the dynamic numerical simulation analysis was performed for the deployment process of antenna from folded state to fully deployed state to analyze effects of rotating damper on unfolding speed and locking impact force during antenna being unfolded in place. Finally, the damping performance test platform of rotating damper was built to conduct damping performance tests. The results showed that the error between the simulated value of damping torque and its test value is within 2%; the amplitude of locking impact load decreases by 91% when antenna is unfolded in place after installing rotating damper, and antenna unfolding speed decreases by 81% at the end of deployment; so, the effectiveness of rotating damper for impact load control is verified. © 2023 Chinese Vibration Engineering Society.
