In this project, one kind of semi-active base isolation system is dealt with, in which a damping-controllable vibration isolator is adopted. The damping-controllability was accomplished by applying Electro-Rheological (ER) fluid to the isolator. ER fluid is known as a class of highly functional material whose apparent viscosity can be varied in response to the applied electric field. The attractive characteristics of ER fluid are wide variation of apparent viscosity and quick response time. The viscosity can be varied several tens times or hundreds times compared with the value obtained without any electric field when subjected to some electric field. The response time is said to be as short as several milliseconds.A prototype vibration isolator was constructed and its performance was investigated. The experiments were conducted under the condition of constant vibration amplitude, in which a detailed investigation was made into the efficiency of ER damper for a small amplitude vibration. Conclusions obtained are as follows ; (1) Stiffness as well as damping capacity of the present vibration isolator can be varied by controlling the applied electric field strength. (2) An idealized model was proposed for the present type of vibration isolator. (3) The damping controllability was shown to be dependent on the vibration amplitude.

本项目研究的是一种半主动基础隔振系统，采用阻尼可控隔振器。阻尼可控性是通过将电流变 (ER) 流体应用于隔离器来实现的。电流变流体被称为一类高功能材料，其表观粘度可以根据所施加的电场而变化。 ER 流体的吸引人的特性是表观粘度变化范围大和响应时间快。当受到一定的电场时，与没有任何电场时获得的值相比，粘度可以变化数十倍或数百倍。据说响应时间短至几毫秒。我们构建了一个原型隔振器并研究了其性能。实验在恒定振幅条件下进行，详细研究了ER阻尼器对于小振幅振动的效率。得到的结论如下； (1)可以通过控制所施加的电场强度来改变本隔振器的刚度和阻尼能力。 (2)针对现有类型的隔振器提出了理想化模型。 (3) 阻尼可控性取决于振动幅度。
