The invention belongs to the technical field of aircraft flight tests, and relates to a typical damage monitoring device and method for load test flight. The typical damage monitoring device comprises a loading actuator cylinder (1), an environmental box (2), a fixed constraint (4), a test loading piece (5) and a damage feature (6), the test loading piece (5) is an aluminum alloy box section, the upper skin of the box section is divided into three pieces, and the upper skins at the two ends of the box section are non-detachable skins and are connected with front and rear beam flanges and rib flanges through rivets; the upper skin of the middle section can be independently detached, a bolt and supporting plate nut connecting mode is adopted, and the piezoelectric sensor network array is arranged in the test process, and damage and damage characteristics of the upper skin structure are monitored; the middle section of the test loading piece (5) is arranged in the environment box (2); the loading actuating cylinder (1) acts on the free end of the test loading piece (5); and the other end of the test loading piece (5) is fixed through the fixing constraint (4).
本发明属于航空器飞行试验技术领域,涉及一种面向载荷试飞的典型损伤监测装置及方法。典型损伤监测装置包括:加载作动筒(1)、环境箱(2)、固定约束(4)、试验加载件(5)、损伤特征(6),其中,试验加载件(5)为铝合金盒段,盒段的上蒙皮分为3块,其中两端的上蒙皮为不可拆卸蒙皮,通过铆钉与前后梁凸缘、肋凸缘连接;中段的上蒙皮可单独拆卸,采用螺栓+托板螺母连接方式,用于在试验过程中布置压电传感器网络阵列,监测上蒙皮结构的损伤,损伤特征(6)制取在中段的上蒙皮;试验加载件(5)的中段设置在环境箱(2)内;加载作动筒(1)作用在试验加载件(5)的自由端;试验加载件(5)的另一端通过固定约束(4)固定。
