| 摘 要： | 本文作者设计制造了一种高效被动阻尼控制（HEDC）装置和一种半主动控制装置－主动变刚度，阻尼（AVS．D）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，HEDC控制效果是令人满意的，而AVS．D控制则可以获得更好的效果，尽管它仅需很少的能量输入，试验结果表明，在AVS．D控制中，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AVS．D控制系统是通过阻尼而不足刚度来控制受控结构，这在一定程度上降低了控制时滞的影响。 |

| Abstract: | A highly efficient damping control (HEDC) device and an active variable stiffness/ damping (AVS.D) control device are designed and manufactured, and simulating earthquake shaking table tests of the two control devices are carried out by the authors of the paper to examine their control mechanism and effectiveness. The results of the tests show that (1) the control effectiveness of the HEDC device is significant, and it is highly efficient compared with usual dampers; (2) although a little amount of energy is inputted into it, a better control eftectiveness is obtained by the AVS.D control device; and (3) most of the time, the AVS.D control device works in variable damping state to reduce the vibration of the controlled structure. This indicates that the influence of time delay is small in the device. |
