| Popis: | The strength study of composite flywheel is an necessary part for flywheel energy storage technology. The drive and bearing technology are the key challenges for a high vacuum and high-speed spin test device. The dynamics of the flywheel rotor-bearing-damper directly determines whether the flywheel can be accelerated to the test speed and runs stably. For these reasons, a flywheel spin test system with small stiffness lower support but no upper support was established. By means of the Lagrangian equation, the dynamic model of the flywheel rotor-bearing-damper was built to calculate critical speeds, modal shapes and modal damping ratios with different speed. The supports' function and their effects on the modal damping ratios and forced vibration were also discussed. The results show that the spin test system without the upper support is simple, efficient and runs stably at the high speed. |
