Aircraft main landing gear emergency breaking test bed and test method

The invention provides an airplane main landing gear emergency breaking test bed and a test method. The test method comprises the following steps: arranging a plurality of breaking pins on the main landing gear according to a main landing gear mounting structure and emergency breaking requirements; loading a load on a wheel shaft of the main landing gear, wherein the direction and the size of the loaded load are changed according to actual working conditions; when the loaded load reaches the limit load Fu, keeping the load for a certain time and keeping no breaking; continuously loading the load to break the breaking pins, recording the breaking load, and obtaining the breaking sequence of the breaking pins; and comparing the obtained breaking sequence and breaking load of each breaking pin with the preset breaking sequence and breaking load, if the obtained breaking sequence and breaking load are consistent with the preset breaking sequence and breaking load, proving that each breaking pin is reasonably desi
