The invention belongs to the field of undercarriage structure design, and particularly relates to an undercarriage emergency disconnection static load verification device. Comprising a test bed, a test bottom plate and an undercarriage test piece. A course loading actuating cylinder is mounted on the test bed; a vertical loading actuating cylinder is mounted on the test bottom plate, and a first bottom plate connecting part, a second bottom plate connecting part and a third bottom plate connecting part are further mounted on the test bottom plate; and the undercarriage test piece comprises a supporting column, an airplane wheel fake piece, a first inclined supporting rod and a second inclined supporting rod. According to the undercarriage emergency disconnection static load verification device, secondary design is performed on the emergency disconnection shaft pin by using the reduced disconnection load, an emergency disconnection static load test is performed by using the undercarriage and the shaft pin which is reduced in an equal proportion, and the undercarriage emergency disconnection static load verification device is improved on the premise that the undercarriage emergency disconnection load and sequence verification requirements are met. The test load requirement in the static load verification test is greatly reduced, so that the test cost is reduced, and the safety is improved.
本申请属于起落架结构设计领域,特别涉及一种起落架应急断离静载验证装置。包括:试验台架、试验底板以及起落架试验件。所述试验台架上安装有航向加载作动筒;所述试验底板上安装有垂向加载作动筒,所述试验底板上还安装有第一底板连接部、第二底板连接部以及第三底板连接部;起落架试验件,所述起落架试验件包括支柱、机轮假件、第一斜撑杆以及第二斜撑杆。本申请的起落架应急断离静载验证装置,通过利用减缩后的断离载荷对应急断离轴销进行二次设计,利用起落架和等比例缩减后的轴销进行应急断离静载试验,在满足起落架应急断离载荷及顺序验证要求的前提下,大大降低了静载验证试验中的试验载荷要求从而降低试验成本并提高安全性。
