The invention belongs to the technical field of airplane structure detail durability test, and discloses a frame joint structure test piece connected with an airtight top plate and a test method, which are used for verifying and examining the key structural detail of a frame joint connected with the airtight top plate, and ingeniously bypassing the complicated design and time consumption which originally need large-scale full-size test verification. Structural details influencing main life indexes of the structure are quickly stripped, small test pieces are adopted for the structural key details, and structural detail durability test verification work can be carried out through a standard testing machine.
本发明属于飞机结构细节耐久性试验技术领域,公开了一种与气密顶板连接的框接头结构试验件及试验方法,用于验证考核与气密顶板连接框接头这一结构关键细节,巧妙的绕开了原本需要大型全尺寸试验验证的繁杂设计与时间消耗,将影响该结构主要寿命指标的结构细节快速剥离出来,对结构关键细节采用小型试验件,通过标准试验机即可开展该结构细节耐久性试验验证工作。
