摘要
Abstract
As a complex mechanical-electrical-hydraulic coupling device,the civil aircraft rudder actuator is subject to complex loading conditions,and the structural fatigue damage behavior is special compared with that of the airframe structure.To ensure the actuator structural loading capacity,and then ensure the normal function of the actuator,it is necessary to establish reasonable structural inspection intervals,and carry out the necessary inspections on the actuator structure.In this paper,based on the requirements of airworthiness regulations,the method of determining inspection intervals under single crack and widespread fatigue damage was studied for the rudder actuator structure of civil aircraft,and it was proposed that the smaller of the threshold values calculated by fatigue life principle and crack propagation life principle can be used as the final inspection threshold of actuator structure of civil aircraft,and it also analyzed and identified the risks of inspection intervals,and proposed the points of concern for the inspection intervals.The conclusion of the analysis shows that the inspection interval method is a safe and conservative assessment method for single crack and widespread fatigue damage,especially for actuator structures with complex fatigue behaviors where the crack extension pattern cannot be obviously judged,and it can provide theoretical and engineering guidance for the establishment of inspection intervals for the structures of complex mechanical-electrical-hydraulic coupling equipment such as rudder actuators.关键词
