The invention adopts a technical scheme that: a fuel tank cap fatigue test bed is composed of a fatigue test device, a U-shaped support and a base, wherein the fatigue test device can simulate the situation that a person opens and closes an oil tank cap of an entity vehicle in the actual life; and the requirements of oil tank caps of different vehicle types for different height positions are met by adjusting the position of a sliding block on the U-shaped support. At the beginning of a test, a push rod is in an extending state, one end of a nylon rope is fixed to the oil tank cap of the entityvehicle, and the other end is fixed to an unthreaded hole of the pulley. According to the fuel tank cap fatigue test bed, an electric cylinder data instruction in the fuel tank cap fatigue test bed is given by a computer, the push rod contracts, the fuel tank cap of the entity vehicle is stretched to a limit angle by means of the nylon rope, then the computer gives an electric cylinder data instruction again, the push ro
