Research on Degradation Behavior of Airborne Mechano-electronic Products

摘要

Dne to the complex working and storage environment for airplanes, the consumptive failures of airborne mechano-electronic products are unavoidable. Aiming at the problem that degradation behaviors that cause this kind of failures are frequently neglected, based on the concept of degradation for airborne mechano-electronic products, a new method of conducting research that treats aging process as a critical degradation behavior is presented. According to the characteristics of airborne mechano-electronic products, steering engine is defined as a critical airplane airborne mechanoelectronic product. Through detailed analysis of the vulnerable area of steering engine, the failure mechanism of aging of steering engine rubber seal is discussed. The degradation model of steering engine rubber seal is presented. Finally, feasibility of the method that replaces the research of degradation behavior of the airborne mechano-electronic products with that of aging is verified.
