Abstract
This paper presents the dynamic response and analysis of a dynamic resistor in a rotating system which is sensitive to the vibration of the rotating system. The sensitivity of the dynamic resistor is adjusted in order to stabilize the rotating system when acted upon by various excitation input functions. The equations of motion of the dynamic resistor and the rotating system, derived by the use of the energy method, result in coupled nonlinear differential equations, and the response of the dynamic resistor is highly correlated to the vibration of the rotating system.
In this paper, the derivation of equations of motion of the dynamic resistor and the rotating system and their dynamic responses are analyzed in order to determine the optimal design parameters that provide stability for the rotating system when it is excited by external input forcing functions. The dynamic response is obtained both by experimental data and computer simulation. The experimental data indicate that the sensitivity of the dynamic resistor is related to the vibrating response of the rotating system and the rotational system parameters including the natural frequency.
The dynamic response obtained by computer simulation is compared with the experimental data. The computer simulation results are to be used to determine the optimal values of the parameters of the dynamic resistor with respect to the rotating system.
The uniqueness of this system is that the dynamic resistor is completely isolated from other inputs except the rotational vibration of the rotating system. The conclusions include recommendations and areas for future research.
