The Change of Behavior of Magnetorheological Damper with a Single-Stage Meandering Valve After Long-Term Operation (original) (raw)

Proceedings of the 6th International Conference and Exhibition on Sustainable Energy and Advanced Materials, 2020

Abstract

A magnetorheological (MR) damper with meandering valve type is known for its capability to produce higher force than other MR valve types while maintaining the compactness. It is essential to investigate the properties of MR damper in long-term operation. Therefore, this paper aims to investigate the MR damper with single-stage meandering valve performance after long-term operation. The experiment will be executed by applying the usage of MR fluid in a bypass double-ended damper. Firstly, the damper was characterized to know the initial damper performance. Secondly, the damper performance will be observed in long-term operation up to 100,000 cycles. Based on the force versus displacement graph, the peak to peak force has increased by about 33.3% after 28,000 cycles. In other words, the damper becomes stiffer after a long-term operation test will affect the performance of MR damper.
