Self-synchronization of Two Unbalanced DC Motor-Driven Rotors on a Common Movable Platform

Abstract

A pair of identical unbalanced rotors, independently driven by two separate DC motors, is placed on a common movable platform. The assembly is designed as an SDOF spring-mass-damper system and the modeling is done entirely on MSC Adams. For a set of predefined system parameters, the voltage values for both motors are operated manually and separately. Both motors are defined as nonideal drives with inadequate power supply. With the help of simulated responses, the Sommerfeld effect along with the phenomenon of self-synchronization is studied numerically, with an aim to attenuate large amplitude vibrations for the movable platform.
