Intelligent Vibration Isolation and Mitigation of a Platform by Using MR and VE Devices
Publication: Journal of Aerospace Engineering
Volume 29, Issue 4
Abstract
The vibration isolation and mitigation of a platform, such as aerospace or precision instrument platforms, is an important research topic. However, previous studies only address high-frequency excitations; they disregard the control effect of low-frequency excitations. Thus, a new vibration control scheme for a platform is proposed to reduce the dynamic responses of a platform that is subjected to wide-frequency excitations, which range from 0 to 500 Hz, using vibration isolation and mitigation devices, magnetorheological (MR) dampers, and viscoelastic (VE) dampers. The motion equations of a complex dynamic system with these three different types of dampers are deduced considering seven degree-of-freedom coupling vibration. The idea of multistate control is adopted to control the inputting currents of the MR damper, and the dynamic responses of the platform to sinusoidal excitation, white noise excitation, and load spectrum excitation are calculated, respectively. The analysis results indicate that the proposed vibration control scheme is effective and suitable for vibration control of the platform.
