Maxwell型セミアクティブダンパの振動制御能力に関する基礎的考察

抄録

The objective of this paper is to clarify the maximum control capacity of the Maxwell-type semi-active damper to develop an effective system for structural control. We focus on the force-displacement orbit to understand and consider the physical constraint inherently associated with the Maxwell model. The key conclusions are as follows: 1) A semi-actively controlled damper can realize twice as much damping augmentation as a passive damper. 2) A simple on/off control scheme is the best strategy for energy dissipation or displacement reduction. 3) There is an optimum control parameter that minimizes the acceleration or the story shear force, and this parameter can be directly obtained in accordance with the system stiffness condition.
