The invention belongs to the technical field of aircraft structure design, and particularly relates to a bird impact test piece. The test piece comprises a composite flat plate (5), an inner pressing plate (4), an outer pressing plate (6) and a plurality of composite partition plates, wherein the composite flat plate (5) is provided with a plate surface for bearing bird impact; the inner pressing plate (4) and the outer pressing plate (6) are of frame structures and are connected to the two sides of the plate face of the composite flat plate (5) in a pressed mode respectively, and the inner pressing plate (4) is connected with a test clamp. Each composite partition plate comprises a composite partition plate web plate (1), a lower edge strip and side edge strips (2), the plate surface of the composite partition plate web plate (1) is perpendicular to the plate surface of the composite flat plate (5), the composite partition plate web plate (1) is connected with the composite flat plate (5) through the lower edge strip (3) at the bottom, and the composite partition plate web plate (1) is connected with the test fixture through the side edge strips (2) on the two sides. The bird impact test structure of the airplane with the composite partition plate is simplified, and the test reliability is improved.

    本申请属于飞机结构设计技术领域,特别涉及一种鸟撞试验件。该试验件包括:复材平板(5)、内压板(4)、外压板(6)及多个复材隔板,复材平板(5)具有承载鸟撞的板面;内压板(4)与外压板(6)为框体结构,分别压接在复材平板(5)的板面两侧,内压板(4)与试验夹具连接;每个复材隔板包括复材隔板腹板(1)、下缘条及侧缘条(2),复材隔板腹板(1)的板面垂直于复材平板(5)的板面,复材隔板腹板(1)通过底部的下缘条(3)与复材平板(5)连接,复材隔板腹板(1)通过两侧的侧缘条(2)与试验夹具连接。本申请简化了飞机带复材隔板的鸟撞试验结构,提高了试验可信度。
