The invention belongs to the field of unmanned aerial vehicle wing tubular beam design, and relates to a large-specification anti-bending circular section wing tubular beam butt joint structure which comprises an inner side circular tubular beam, an outer side circular tubular beam, an inner side butt joint arranged at the end of the inner side circular tubular beam in a sleeving mode and an outer side butt joint arranged at the end of the outer side circular tubular beam in a sleeving mode. An inner side end rib is arranged on the inner side circular tube beam, and an outer side end rib is arranged on the outer side circular tube beam; the inner side circular tube beam and the inner side end rib are connected through the inner side butt joint, the outer side circular tube beam and the outer side end rib are connected through the outer side butt joint, and the inner side butt joint and the outer side butt joint can transmit large-specification bending moment and shearing force. Meanwhile, the inner side butt joint and the inner side end rib as well as the outer side butt joint and the outer side end rib are simply matched, so that the structure can be quickly disassembled and recovered to be installed, the structure maintenance is excellent, the implementation effect is good, the reliability is relatively high, and the wing spar and butt joint type selection static test and the flight verification of the solar unmanned aerial vehicle are passed.
本申请属于无人机机翼管梁设计领域,为一种大规格抗弯圆型截面机翼管梁对接结构,包括内侧圆管梁、外侧圆管梁、套设于内侧圆管梁端部的内侧对接接头和套设于外侧圆管梁端部的外侧对接接头;内侧圆管梁上设有内侧端肋,外侧圆管梁上设有外侧端肋;通过采用内侧对接接头分别连接内侧圆管梁和内侧端肋,采用外侧对接接头分别连接外侧圆管梁和外侧端肋,内侧对接接头和外侧对接接头能够传递大规格弯矩和剪力,同时由于内侧对接接头与内侧端肋、外侧对接接头与外侧端肋配合简单,能够实现结构的快速拆卸和恢复安装,且具有优异的结构维护性,实施效果良好,可靠性也较高,已通过机翼翼梁及对接选型静力试验,以及太阳能无人机的飞行验证。
