摘　　要：提出了相邻结构高效阻尼控制的概念，并基于双液缸的放大原理提出了一种相应的装置。该装置通过放大相邻结构间的振动差别，使阻尼器具有更大的变形和速度，从而更高效地工作。文章阐明了该装置的工作原理，建立了两相邻结构高效阻尼控制体系的运动方程，并对此进行了计算机仿真分析。结果表明，高效阻尼控制的概念是正确的，本文提出的控制装置是有效的，可取得远优于普通阻尼控制的效果。The concept of high-efficient damping control of adjacent structures and the corresponding controllers based on the amplified principle of two liqid cylinders are put forward in the paper. The controller can increase the relative deformation and velocity of the damper by amplifying response between the adjacent structures and make the damper do its best. The control mechanism of the controller is expounded and motion equations of the combined structure system are established. Computing simulation is carried out to analyze and discuss the control effect of the controller. Results show that the concept of high-efficient damping control is correct and the corresponding controller is efficient. It can attain much higher control effect than a usual controller.
