The invention provides an aviation structure strength test loading device. The aviation structure strength test loading device comprises a test constraint base, an outer cylinder simulation and constraint device, a rotation constraint device and an airplane wheel simulation device, a piston rod of the test piece (1) is sleeved in the outer cylinder simulation and restraint device, and the outer cylinder simulation and restraint device is fixed on a base platform (2) of the test restraint base; one end of the rotation restraint device is fixed on the standard column section (3) of the test restraint base, and the other end is connected with the test piece (1); the two ends of a wheel shaft of the test piece (1) are respectively connected with an airplane wheel simulation device, and each airplane wheel simulation device is provided with four convex corners. And each direction loading actuating cylinder is connected with the convex corners of the two airplane wheel simulation devices. The problems that an existing piston rod strength test is high in cost, large in loading error and the like are effectively solved.
