The invention provides a wheel pair test forcing device and a wheel track test system. The wheel pair test forcing device comprises a support assembly comprising a rolling element, a first support, an elastic member, a second support and a locking member. The outer peripheral surface of the rolling element is pressed against the top surface of a support beam, one end of the elastic member acts on the rolling element, the other end of the elastic member acts on the first support, the first support is fixedly connected to the second support, the second support is located below the support beam, the second support is fixedly connected to a first actuator, the first support member is fixedly connected with the support beam when the locking member is locked, and the first support member is translated upwardly from the support beam under the tension of the elastic member after the locking member is released. The wheel track test system comprises the wheel pair test forcing device. A rail wheel assembly capable of supporting rail vehicle wheel pairs is arranged below the first actuator. The present invention is capable of efficiently adjusting the position of the vertical loading force applied to the wheel pair and can reduce the cost of the test.
Description
technical field [0001] The invention belongs to the technical field of wheelset testing of rail vehicles, and in particular relates to a wheelset testing booster and a wheel-rail testing system. Background technique [0002] The rail vehicle wheelset test device mainly simulates an infinitely long track through the rail wheel, directly drives the rail wheel with the drive motor to drive the tested wheelset to run, and loads the wheelset vertically through the actuator to simulate the actual running state of the train. During the test, the lateral and longitudinal actuators can be used to excite the vibrations to study the performance of the axles, bearings, axle boxes, gearboxes, motors and other components under the condition of rolling vibration; the load motor can apply a reverse torque to the tested wheel pair to realize the simulation Various complex states in the process of traction and braking of the train line; at the same time, the speed, acceleration, wheel-rail fo...
