摘要
针对航空壁板结构同时承受常规疲劳载荷与振动载荷的受载特点.通过一种新的联合加载试验装置解决常规疲劳载荷与振动载荷同时施加的技术难题.开展航空壁板结构的联合加载试验技术研究.试验结果表明论文提出的联合加载方法可行.并验证损伤等效方法的有效性。
This article for fuselage panel under conventional fatigue load and vibration load,through a new joint load test device to solve the problem,combining test loading of conventional fatigue and vibration load at the same time,carry out the combined test loading technology research.The experiment results showed that the proposed joint load method is feasible,and verify the validity of the damage equivalent method proposed.
