The utility model discloses an experiment table for vehicle suspension performance. The experiment table comprises walking devices, a lower crossbeam, an upper crossbeam, a vibration-damping suspension frame, a revolution device, a driving device, a pedestal, a vibration testing system, an annular simulated pavement and a pedestal installation flange, wherein the pedestal installation flange is arranged at the inner side of the annular simulated pavement, the pedestal is connected with the pedestal installation flange via bolts, the lower crossbeam is supported by the annular simulated pavement via the walking devices which are respectively mounted at the two ends of the lower crossbeam, the revolution device is vertically arranged at the inner side of the annular simulated pavement, and the middle portion of the upper crossbeam and the middle portion of the lower crossbeam are connected with the revolution device via a structure which can slide up and down. The experiment table has the advantages that a 1/2 vehicle module is used for simulation, the annular simulated pavement is arranged in a matched manner, the driving device drives the upper and lower crossbeams, which are supported by the annular simulated pavement via tyres and the vibration-damping suspension rack, to rotate via the revolution device, a more practical driving state can be simulated, the experimental reliability is improved, and the experimental precision is increased.
