| Abstract: |
| In order to accurately formulate the reliability test profile of equipment in the affected area of aircraft engine, a design method for reliability test profile is proposed.According to the vibration characteristics of the equipment in the affected area of aircraft engine, which is consisting of broadband random signals and narrowband spike signals, the engineering interception equivalent method is used to analyze and summarize the measured vibration data to obtain the vibration test spectrum. Then, according to the duration of the typical mission state of the aircraft and the time proportion of the entire mission profile, the vibration stress conditions are obtained according to the simplification principle proposed in the article and the reliability test profile is synthesized. By using this method to process the vibration data of equipment near an aircraft engine, the reliability test profile of the equipment in the affected area of aircraft engine is obtained. The engineering interception equivalent method proposed in this paper is very suitable for the separation and induction of vibration signals of equipment near the engine. The reliability test profile design method proposed in this paper provides a new idea for the reliability profile design of equipment in the aircraft engine affected area, and is of great significance for the reliability design of equipment in the aircraft engine affected area. |
