| description | The utility model belongs to the technical field of axle testing, and particularly relates to a rail transit vehicle axle three-point bending fatigue testing device which comprises a mounting seat, a support is arranged on the mounting seat, and two axle bases used for supporting an axle are arranged on the upper surface of the support side by side. Actuating cylinders are symmetrically arranged on the left side and the right side of the support, force sensors are connected to the upper ends of the actuating cylinders, connecting rods are hinged to the upper ends of the force sensors, the upper ends of the two connecting rods are hinged to the two ends of a pressing plate respectively, and the middle of the pressing plate makes contact with an axle and is used for applying pressure to the axle. The axle is supported by the two axle bases, and sine load is applied to the middle of the axle through the actuating cylinders arranged on the left side and the right side, so that the three-point bending fatigue test |
