摘要
在已有电磁摩擦控制装置性能试验的基础上 ,根据 1∶4五层钢框架结构模型设计制作了电磁摩擦耗能装置。该装置可以根据结构控制层的层间位移来调节工作电流 ,实现控制力变化连续、可逆、迅速 ,因而克服了普通摩擦耗能装置控制力不可变的不足。分别将装置安装在底层柔性结构模型和普通结构模型上进行了地震模拟振动台试验。大量振动台试验结果表明 ,电磁摩擦耗能装置用于结构被动控制具有良好的可靠性和适应性 ;是一种新型、有效的摩擦耗能装置。
Based on former performance capacity experiments of electromagnet-friction control devices, the EMF energy dissipation devices are designed and manufactured, according to a 1∶4 five-story steel frame model.The EMF energy dissipation can realize continuously variable,rapid and reversible control force,and thus over come the shortcoming of the commonly used energy dissipaton devices whose control forces are invariable.The devices were fixed,respectively,onto the flexible first story and the ordinary structure model,and the shaking table tests were carried out.The test results demonstrated that the EMF energy dissipation device has good reliability and adaptability for passive control.
