This project is on a variable-damping dynamic absorber applying Electrorheological (ER) fluid to the damping element of a conventional-type dynamic absorber. A prototype of variable-damping dynamic absorber was constructed and its performance was verified with a three-story structural model. The special ability of the present dynamic absorber is to reduce the vibration amplitude at several frequencies by a single dynamic absorber. 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 absorber. The numerical simulations show good agreements with the experimental results.

该项目是在可变阻尼动态吸收器上，该吸收器将电流动性（ER）流体应用于常规型动态吸收器的阻尼元件。构建了可变阻尼动态吸收器的原型，并通过三层楼层的结构模型验证了其性能。本动态吸收器的特殊能力是通过单个动态吸收器在几个频率下降低振动幅度。 ER流体是功能性流体，可以通过施加的电场强度改变屈服剪切应力。由于其特殊的特性，ER流体已应用于各种机械组件，例如减震器和发动机支架，用于车辆，离合器，阀等。传统的机械组件通过有效地与它们结合在一起。从这个意义上讲，本文显示了ER流体在常规型动态吸收器中的成功应用。引入了由用于系统识别和控制器网络的前向模型网络组成的自适应神经网络控制系统，以控制动态吸收器的可变阻尼元件。数值模拟与实验结果达成了良好的协议。
