摘　　要：通过对武器挂架结构受力分析,确定挂架结构关键受载剖面,并粘贴应变计。通过地面标定试验和飞行试验,获得武器挂架应变/载荷动态值和静态值,分析了挂架载荷随直升机典型飞行状态的变化规律,为武器挂架的结构改型、寿命评估、编写相关的技术说明书提供依据。The method of pylon loading was presented through the analysis based on the strain gauge installation and the flight test. The static strain range, the dynamic strain range and the characteristic of structure dynamics of the bracket loading were obtained. Then the load time history, its variety tendency as well as the relation related to the helicopter status for the static loading and the dynamic loading of bracket were analyzed. The results provide an important proof for the bracket loading spectrum, strength design, the evaluation of fatigue life and related instruction.
