Research on the Calculation Method of Fatigue Life of Piston Rod Thread under the Pressure Pulse in Aviation Hydraulic Accessories
The internal forces in the thread section of the piston rod which is under the pressure pulse are obtained based on the working principle of the Aviation hydraulic Accessories.Then the fatigue life of the thread is calculated.It is proved that this method which is used to evaluate the fatigue life of the thread is effective by comparing with the results of the pressure pulse experiment.
