High speed rolling contact rigidity and damping coefficient tester

The utility model discloses a high speed rolling contact rigidity and damping coefficient tester, to be that the driving shaft is horizontal install on the workstation principle of this tester, the driving shaft passes through resilient coupling and establishes ties with no linear acceleration transducer, drive by AC servo motor 1, driving pulley drives drive shaft rotating through synchronous circular arc notched belt and from the driven pulleys transmission, it accompanies examination main shaft synchronous revolution to drive through the band pulley transmission simultaneously, accompany the examination main shaft to install in lever holder one end, the lever holder uses the transmission shaft to do the lever motion in order to transmit experimental power as the fulcrum, power amplifier's input interface and signal generator are connected, output port is connected with the non -contact vibration exciter, the non -contact vibration exciter of fixing in the excitation box lasts for sample forced vibration as
