Since full active control needs complex and heavy elements, semi-actively controlled landing legs which use only variable damping elements are advantageous. In this paper, the configuration and the control law of a semi-actively controlled landing leg system are presented.Tatsuaki.Hashimoto...

The semi-actively controlled MR-suspension employs the "on-off" control law in response to direction of the damper velocity, so as to generate the asymmetric damping force property form the symmetric MR-damper design. The resylts show that the MR-damping hysteresis yields serious transients and ...

Performance of Semi-actively Controlled Building Frame Using MR Damper for Near-Field Earthquakesdoi:10.1007/978-981-13-0365-4_34Most of the studies on the control of building frame using MR damper are investigated for far-field earthquake records, and a considerable reduction in responses is ...
This paper introduces a lightweight design of a shell end milling tool with an integrated semi-active damping system based on magnetorheological fluids. The investigations show that this approach allows an adjustment of the dynamic behaviour of the tool. In machining experiments a significant increase...
