The invention relates to an aircraft dynamic scale model landing gear bumper spring design method. The method comprises the following steps of 1, estimating a ground load and calculating landing gear loads, wherein the landing gear loads comprise a nose landing gear load Fn and a main landing gear load Fm; 2, scaling the size of a landing gear bumper according to a predetermined proportion; 3, fitting a static pressure curve of the landing gear bumper into a linear curve; 4, determining bumper spring design constraint parameters according to a predetermined proportion; 5, establishing a bumper spring effective parameter calculation formula; 6, iteratively computing bumper spring effective parameters; and 7, selecting an optimum parameter group. According to the aircraft dynamic scale model landing gear bumper spring design method, landing gear bumpers can be simplified to the greatest extent under the premise of ensuring the mechanical properties and model sizes of the landing gear bumpers, aircraft dynamic scale model landing gear bumpers are designed most really, the design and processing costs are reduced, and the dynamic requirement and similarity requirement are satisfied.
