Abstract
The vibration frequency characteristics of a rotor system are directly related to the moment of inertia of the system. In this paper, a moment of inertia adjustment device based on electromagnetic control is proposed to adjust the frequency characteristics of the rotor system and better reduce vibration by changing the moment of inertia. First, the finite element simulation model is established, and the electromagnetic field of the electromagnetic control unit in the device is analysed. The influence of materials and parameters of the main parts on the electromagnetic field is discussed. Then, the validity of the finite element simulation results for the electromagnetic control unit is tested by experiments. Finally, the variation of the displacement and force of the moving mass and the changes with speed in the device’s moment of inertia under different magnitudes of electrical current are analysed. The results show that the proposed moment of inertia adjustment device can be used to finely adjust the moment of inertia, which enables better control of vibrations in rotor systems.
