Take connecting device's viscous damper

The utility model discloses a take connecting device's viscous damper couples together the viscous damper piston rod through connecting device with acceleration sensor, connecting device be the steel sheet shaping jig, the sensor bonds on the steel sheet shaping jig, the steel sheet shaping jig uses the steel processing that has certain rigidity and toughness to form, the steel sheet shaping jig divide into chisel trace linkage segment and smooth test section, and just smooth test section is processed along the piston rod direction of motion and is buckled, and is perpendicular with the piston rod, becomes 90 degrees contained angles with the horizontal plane, the steel sheet is fastening bolt and viscous damper piston rod rigid connection one -tenth an organic whole for the shaping jig, does not produce any relative slip mutually. The utility model discloses it has had conventional test instrument and test equipment on current phase to utilize, realizes the real -time test of the ration of attenuator inside dynamic characteristics and motion state through outside technological means, effectively solves the technical problem that viscous damper dynamic performance is difficult to the test in the shaketalle test.
