Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
One, the structure setting of the utility model
Referring to attached drawing 1-3.The utility model discloses a kind of half active pendulum type friction type quality coordination damping devices, including
Arcuate friction sliding slot 1,3, three swing rods 2 of rocker and three mass blocks 4；
Three sliding slots that wide and bottom is coated with solid layer of molybdenum-disulfide, each cunning are provided in arcuate friction sliding slot 1
The both ends of slot are provided with high-damping fiber rubber 9；One end of swing rod 2 is provided with through-hole, the upper surface rigidity of the other end and mass block 4
Connection；The duct vertical with swing rod 2 is provided in mass block 4, skeleton sleeve 7 is placed in the duct of mass block 4, under mass block 4
