The invention relates to a comprehensive test platform for running attrition test of box components and for static balance test of wheel and shaft parts. The comprehensive test platform comprises a platform with an upper reference plane, a static balance test device, a running attrition test device, an oil adding and pumping device and T-shaped grooves provided arranged on the platform at intervals. The static balance test device is composed of two core shaft supports, core shafts, a pair of rollers connected with each core shaft support, wherein the core shafts are arranged on two pairs of rollers on both ends. The running attrition test device includes a power device, a transmission mechanism and two press plates, wherein, the power device is connected with the transmission mechanism, and the transmission mechanism is connected with an input shaft of a box body to be tested. The oil adding and pumping device comprises an oil tank, a motor and a gear pump, wherein, the suction inlet of the gear pump is connected with the pipe line of the oil tank; the exit hole of the gear pump is connected with a hose joint and an oil nozzle. All fixed elements on the platform are connected with the platform through T-shaped screws. The invention has the advantages of accurate testing, good generality, good practicality, simple structure, convenient fabrication and low cost.
