摘要

This paper describes a variable-damping dynamic damper applying Electrorheological (ER) fluid to the damping element of a conventional-type dynamic damper. A prototype of variable- damping dynamic damper was constructed and its performance was verified with a three-story structural model. The special ability of the present dynamic damper is to reduce the vibration amplitude at several frequencies by a single dynamic damper. ER fluid is functional fluid whose yield shear stress can be changed by the applied electric field strength. Because of its peculiar property, ER fluid has been applied to various mechanical components such as shock absorbers and engine mounts for vehicles, clutches, valves, etc. One of the practical ways in applying ER fluid to mechanical components may be to expand the performance of conventional mechanical components by combining ER fluid effectively with them. In this sense, this paper shows a successful application of ER fluid to a conventional-type dynamic absorber. An adaptive neural network control system composed of a forward model network for system identification and a controller network was introduced to control the variable-damping element of the dynamic damper. The numerical simula- tions show good agreements with the experimental results.
