Investigation on influence factors of optically controlled electrorheological fluid damping system

Abstract Electromagnetic rheological damping control system, as an important control technology, has been widely used in braking, vibration reduction, micro-valve etc. However, the electromagnetic rheological damping control system faces electromagnetic interference because of the high-voltage source. To solve this problem, a novel optically controlled electrorheological fluid damping system was proposed in this study. Previous studies have confirmed the feasibility of the optically controlled electrorheological fluid damping control system via numerical simulation and experiment. In this paper, the mechanism and mathematical model of the optically controlled electrorheological fluid damping system are established. Analyses of influencing factors of the optically controlled damping system, especially the impact of light intensity and microchannel size on system performance, are performed through experimental and theoretical methods. Research findings of the analyses of influencing factors provide a comprehensive understanding of the working principle of the electrorheological fluid damping system, thereby promoting stability and reliability in microfluidic technology.
