Aircraft landing gear load calibration method and test fake wheel structure

The invention provides an aircraft landing gear load calibration method and a test fake wheel structure. The load calibration method comprises the steps of replacing a test fake wheel with a genuine wheel, and transferring a calibration load including the heading torque; establishing a mechanical model of the test fake wheel load transfer, and enabling the external force to the test fake wheel to be equivalent to a concentrated load of the center of the test fake wheel, the concentrated load including all components determined by the degree of freedom; and carrying out data processing and the like. The test fake wheel structure comprises a cylindrical structure (1) at the center, four circumferentially distributed outrigger structures (2) extending out radially along the cylindrical structure (1) at the center, and a flange structure (3) extending out from one end of the cylindrical structure (1) at the center and being used for connection with a landing gear. 本发明提供了一种飞机起落架载荷标定方法及试验假轮结构，载荷标定方法包括试验假轮替换真机轮，传递包括
