The invention provides a flight simulator rod force simulation fidelity evaluation device design method. A flight simulator rod force simulation fidelity evaluation device obtained through the design method of the invention can quantitatively evaluate simulation manipulation load system rod force simulation fidelity of a flight simulator according to a comprehensive evaluation index module used in the evaluation method of the simulator rod force simulation fidelity. Through data obtained by a test, correlation coefficient rxy=0.91 of evaluation result of the evaluation device obtained through the design method and aviator subjective evaluation result achieves very good consistency. Therefore, the method is reasonable and reliable. The model parameters of the design method are easy to modify. Therefore, the device obtained with the method can be applied to comprehensive evaluation of the steering wheel control force simulation fidelity of an automobile driving simulator, and can also applied to design of a steering wheel control force simulation fidelity comprehensive evaluation device of the automobile driving simulator.
