飞机主操纵系统疲劳试验载荷监控方法研究——应变数据分析法

A Fatigue Loading Monitoring Method Based on Strain Data Analysis in Primary Flight Control System Fatigue Tests

针对某机全机主操纵系统疲劳试验中动态操纵情况下的应变测量以及试验载荷监控问题进行了分析和讨论,并对基于应变测量数据分析的操纵系统疲劳试验载荷监控方法的确定及其应用效果进行了阐述。在操纵系统疲劳试验过程中的实际监控结果表明,该方法对副翼/平尾/方向舵操纵系统多种试验状态下的试验载荷监控实用有效。

The dynamic strain measurement and test trol system fatigue tests are discussed. A fatigue test ing data analysis and its application to primary flight loading monitoring problems in primary flight conloading monitoring method based on train measurcontrol system fatigue tests is presented. The monitoring results from flight control system fatigue tests show that this method based on strain data anlysis is practicable and effective for several test modes in aileron, elevator and rudder control system tests .
