The invention discloses a propeller blade electro-hydraulic servo loading simulation device which comprises a propeller hub or a propeller variable pitch device, a propeller root simulation piece arranged in the circumferential direction of the propeller hub or the propeller variable pitch device, and a loading device connected with the propeller hub or the propeller variable pitch device through the propeller root simulation piece. The loading control system is used for controlling the loading device to carry out coordinated loading, the loading hydraulic system is used for providing an oil source for the loading device, the simulation system is used for establishing a propeller load model, the simulation system is electrically connected with the loading control system, the loading control system is electrically connected with the loading hydraulic system, and the loading hydraulic system is electrically connected with the simulation system. The propeller load model is established through the simulation system, so that the external load generated in the flight process of the simulated propeller is simulated, the reliability and authenticity of the test are improved, meanwhile, the number of times of test run on a rack is reduced, and the project development cost is reduced.
