Abstract EN
The design, fabrication, and testing of a new double-piston MR damper for space applications are discussed.
The design concept for the damper is described in detail.
The electromagnetic analysis of the design and the fabrication of the MR damper are also presented.
The design analysis shows that the damper meets the weight and size requirements for being included in a space truss structure.
The prototype design is tested in a damper dynamometer.
The test results show that the damper can provide nearly 80 N of damping force at its maximum velocity and current.
The test results also show that the seal drag could contribute significantly to the damping forces.
Additionally, the test results indicate that both the work by the damper and damping force increase rapidly with increasing current at lower currents and taper off at higher currents as the damper starts to saturate.
The damper force versus velocity plots show hysteresis in both pre- and postyield regions and asymmetric forces in jounce and rebound.
A model is proposed for representing the force-displacement, force-velocity, and asymmetric forces observed in test results.
A comparison of the modeling results and test data indicates that the model accurately represents the force characteristics of the damper.
