Abstract
The whole-spacecraft vibration isolation (WSVI) platform can enhance the dynamic environment in the launch loads of rocket launchers during trips into orbit. In this dissertation, non-probabilistic reliability research is conducted for the dynamic characteristics of the integrated active and passive WSVI platform. First, the non-probabilistic reliability theory of the uncertain integrated active and passive vibration isolation system is established. Then, through the first-order equivalent dynamics model for the integrated active and passive WSVI system, the non-probabilistic reliability analysis of the WSVI platform is conducted. Finally, the analyzed accuracy of the non-probabilistic reliability for the WSVI platform is tested by experiments, through which the reliability and security of the integrated active and passive WSVI platform launch are enhanced.
