Bogie primary spring rigidity experiment table

The invention discloses a bogie primary spring rigidity experiment table which comprises an experiment table body, the two sides of the top end of the experiment table body are fixedly connected with the two sides of the bottom end of a frame respectively, a detection mechanism is arranged at the top end of the inner wall of the frame, and bunching mechanisms are arranged on the two sides of the detection mechanism. A bidirectional lead screw is rotationally connected between fixing plates connected with the electric sliding rail, a rotating shaft rotationally connected with a detection supporting plate is connected with a bearing plate, a vertical force sensor is installed on the bearing plate, a corner frame on the detection supporting plate is rotationally connected with a connecting shaft, and a second servo electric cylinder connected with the connecting shaft is provided with a horizontal force sensor through a pressing base. The universal shaping metal hose connected with the connecting column is conne
