Title:
CONTROL SYSTEM EMPLOYING MECHANICAL DRIVING DEVICE TO REALIZE ADAPTIVE ADJUSTMENT OF ROTATIONAL INERTIA
Document Type and Number:
WIPO Patent Application WO/2020/155644
Kind Code:
A1
Abstract:
The present invention relates to the field of vibration suppression systems. Disclosed is a smart control device employing a driving shaft to realize adjustment of rotational inertia. The smart control device comprises a force output module fixedly connected to a controlled structure. The force output module comprises a rotational inertia submodule and a force output submodule. The rotational inertia submodule comprises two symmetrically arranged rotational inertia discs. Three rotational inertia adjustment channels are uniformly radially arranged in each rotational inertia disc. A drive motor, a ball screw and a movable mass block are provided in each rotational inertia adjustment channel. The force output submodule comprises two symmetrically arranged force output devices. The force output device comprises a driving device, an encoder and a speed changer. The present invention employs a driving device to drive a rotational inertia disc so as to generate a control force, such that rotational inertia can be adjusted automatically without needing a frequency regulation process, thereby achieving high adjustment precision and a wide adjustment range. The control system of the present invention is applicable to scenarios in which a structure experiences rotational, torsional or rotary vibrations, and has a wide range of applications and enhanced robustness.
