Design and experimental evaluation of a nylon adaptive flywheel with variable inertia
Shuai Yang,Natalie Baddour,Chuan Li 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.10
This paper proposes an adaptive nylon flywheel, which can achieve passive vibration control by generating variable equivalent mass. With changing rotational speed, the location of sliders in the slots changes, which leads to the creation of variable equivalent mass. Due to the light weight and high strength of the nylon material, a higher changing ratio of equivalent mass can be achieved. To test the behavior of the adaptive nylon flywheel, the inverse screw system was applied to experiments. The accuracy of the mathematical model of the inverse screw system with a nylon adaptive flywheel was verified by experiments. It was experimentally demonstrated that the proposed adaptive nylon flywheel could generate the predicted variable caused by transmission backlash in the inverse screw system. The adaptive nylon flywheel also shows an ability to suppress spike forces under a low frequency and amplitude input. The proposed design and experimental evaluation pave the way towards the passive variable inertial mass control of vibration systems.
