Method for measuring eccentricity of supporting rod

The invention discloses a method for measuring the eccentricity of a supporting rod. The method comprises the following steps: 1) selecting a horizontal workbench; 2) measuring the length L of a staybar with the eccentricity of zero when the aircraft landing gear is unfolded; 3) recording the diameter of each through hole of the stay bar, the diameters of the end parts being [phi]K1 and [phi]K2 respectively, and the diameters of the through holes with the superposed middle parts being [phi]K3; 4) installing two cushion blocks on the workbench, wherein the two ends of the supporting rod are arranged on the two cushion blocks, the height of the cushion blocks guarantees that the centers of through holes in the two ends of the supporting rod are located on the same horizontal plane and the horizontal distance between the centers of the through holes in the two ends is L, and the bottom of the middle through hole is higher than the workbench; 5) measuring the height G1 from the top of thethrough hole in any end o
