Abstract

This study reports on effects of tapered metering pins on a magnetorheological (MR) fluid subjected to shock loading. Using four types of tapered metering pins, we conducted drop impact tests and qualitative analysis of effects of tapered pins on an MR fluid with a magnetic field applied around an orifice area. We measured the displacement of a piston and calculated velocity and acceleration from the measured displacement. The four different tapered pins changed a piston stroke to bring the impacting mass to rest. The results indicated that the shape of the pins has an effect on the entire process of shock absorption, whereas magnetic field strength has an effect on the post-peak behavior only. These results show that a tapered metering pin has applicability to a shock absorber using an MR fluid.
