Method for analyzing anti-fatigue performance of submarine rudderstock mechanism

The invention belongs to the technical field of anti-fatigue analysis methods, and particularly relates to a submarine rudderstock mechanism anti-fatigue performance analysis method. Comprising the following steps: establishing an analysis platform which comprises a rotation and linear motion conversion transmission structure and a power simulation and load simulation mechanism; obtaining a to-be-tested model, and building a temperature compensation system; simplifying the model, calculating the fatigue critical strength factor of the rudderstock, analyzing the fatigue life of the rudderstock in the presence of fatigue cracks, and establishing the relationship among the fatigue life index, the rudderstock toughness coefficient, the fatigue critical strength factor, the cyclic strain hardening index and the elastic modulus of the rudderstock material; the method for analyzing the anti-fatigue performance of the submarine rudderstock mechanism can be used for analyzing and testing the anti-fatigue performance o
