Active vibration reduction system with energy regeneration
Wybrane pełne teksty z tego czasopisma
Studies of the systems with energy regeneration have been carried out for years, since they primarily cover the assemblies with electrodynamic actuators. The paper addresses the issue of active reduction of mechanical vibration using DC motor as the actuator. Testing procedure is aimed to assess potential use of those assemblies in a different frequency band and force range than in electrodynamic actuators. The paper explains the operating principle of the system. The tested vibration reduction system is the physical model of 2 DOF suspension. Initial analysis has been conducted to explore the potential use of the energy produced by the vibration of sprung mass in the second degree of the suspension system in range of high frequencies, for power-supply to the active component incorporated in the same suspension degree in low frequencies range. Results of the experiments revealed that the mechanical parameters of the system can be selected in such a way that for specific interfering signals the accumulated energy should be at least equal to the energy used up by the system.
