Abstract: The present invention relates to a comprehensive test bed for vehicle body, which comprises an vehicle body static strength testing apparatus, an vehicle body air tightness testing apparatus, an vehicle coupler strength testing apparatus and an vehicle body mode testing apparatus, wherein the tested vehicle body is provided with a strain foil and a displacement sensor; and the strain foil and the displacement sensor are connected with a data acquisition system. The comprehensive test bed for the vehicle body can perform an vehicle body static strength test on various rail passenger vehicles, an vehicle body steel structure vibration mode test, an vehicle body partial assembly vibration mode test and an vehicle body air tightness test, and can realize strength tests on partial key components of the vehicle body (a transition vehicle coupler, a return vehicle coupler, an vehicle body chassis cross beam, a hoisting structure, an end structure, and the like).
