โœฆ Synopsis

We propose a new active impact control (or absorber) system that is able to respond to a highly rapid impact and a large #ow rate. The system has advantage over a passive system regarding a feasible pressure and displacement regulation. The impact control system constructs both internal and external dampers, that is its ori"ce is placed inside and outside the hydraulic cylinder. The designed system has a set of logic valves, which respond rapidly to an external impact and are capable of discharging an instant excessive hydraulic #ow, and a servo valve to control the pilot chamber of the logic valve. The impact control system is designed and fabricated based on an appropriate mathematical modelling and its dynamic analysis, and on various control performances. The control performance is veri"ed by simulations and experiments.

This paper presents the "rst application of a semi-active damper system to an actual building. The Semi-active Hydraulic Damper (SHD) can produce a maximum damping force of 1000 kN with an electric power of 70 W. It is compact, so a large number of them can be installed in a single building.

The authors developed a semi-active hydraulic damper (SHD) and installed it in an actual building in 1998. This was the "rst application of a semi-active structural control system that can control a building's response in a large earthquake by continuously changing the device's damping coe$cient. A

A semi-active on-off control policy has been developed to reduce the severity of suspension seat end-stop impacts caused by shocks or high magnitude vibration. An electrorheological fluid damper was used to realize the required two-state damping. The effects of the free travel (i.e., the relative di
