[0025] Such as figure 1 As shown, a double-tuned inertial system includes an installation unit, a liquid inertial damping unit, a first-stage collision-friction tuned mass unit, and a second-stage tuned mass unit.
[0026] The installation unit includes an installation base 15 and a counter force plate 16 , the counter force plate 16 is vertically arranged on the installation base 15 , and the installation base 15 is provided with two slide rail grooves 14 parallel to each other and perpendicular to the counter force plate 16 .
[0027] The liquid inertial damping unit includes a primary liquid inertial unit, a secondary inertial unit and a connecting oil pipe 8 . Wherein, the primary liquid inertial unit includes a large oil cylinder 5, a first piston 6, and a first piston rod 4; the first piston 6 is fixedly connected with the first piston rod 4, and the first piston rod 4 passes through the large oil cylinder 5 and connects with the large oil cylinder 5. The axes of the oi...
