摘要
设计制造了一种半主动控制装置－主动变刚度·阻尼控制装置，并对其控制机理和控制效果进行了模 拟地震振动台试验研究．试验结果表明，尽管该控制装置仅需很少的能量输入，但其可以获得很明显的减震控制效果；在控制过程中，装置的电磁阀处于开启状态工作的时间较长，即在大部分时间里该控制装置是通过阻尼 而不是调频来控制结构的振动，这在一定程度上降低了控制时滞的影响．
An active variable stiffness/damping control device is designed and manufactured, and simulated earthquake shaking table tests of the device are carried out to examine its control mechanism and effectiveness. The results of the tests show that although only a little amount of energy is inputted into the device, significant control effectiveness is obtained, and most of the time, the device works in variable damping state to reduce the vibrations of the controlled structure, which indicates that the influence of time delay is small in the device.
