TMD control system based on rotational inertia virtual translational inertial mass
The invention provides a TMD control system based on rotational inertia virtual translation inertial mass. The TMD control system comprises a fixed block, a mass block, a lead screw, a spring, a flywheel, a sleeve, a ball, a bearing, a main structure and an embedded fixed groove. The fixing block is mounted in an embedded fixing groove of the main structure; the two ends of the lead screw are in shaft connection with the fixing blocks through bearings, so that the lead screw freely rotates in the fixing blocks. The end part of the lead screw is fixedly connected with the flywheel through a bolt; the waist part of the lead screw and the external sleeve form a ball screw sleeve in a preset slide way through a ball; the exterior of the sleeve is fixedly connected with the mass block, and the mass block is arranged on the main structure and connected in a sliding fit mode; and a spring is connected between the fixed block and the mass block. The device is small in occupied space, very small in actual physical mass, good in control effect, convenient to install and popularize and capable of restraining or reducing vibration of the structure.
本发明提供了一种基于转动惯量虚拟平动惯性质量的TMD控制系统，包括固定块，质量块，丝杠，弹簧，飞轮，套筒，滚珠，轴承，主结构，嵌入固定槽；所述固定块安装在主结构的嵌入固定槽内；所述丝杠两端通过轴承与固定块轴接，实现丝杠在固定块内自由转动；所述丝杠端部通过螺栓与飞轮固接；所述丝杠腰部通过滚珠在预定的滑道内与外部套筒形成滚珠丝杠套筒；套筒外部与质量块固定连接，质量块设置在主结构上，采用滑动配合连接；在固定块与质量块之间连接设有弹簧。本发明占用的空间小，实际物理质量很小，控制效果好，安装方便，便于推广，可以达到抑制或减轻结构的振动。
