The invention belongs to the field of unmanned aerial vehicle structure design, and relates to a tapered tubular beam butt joint structure design and preparation method.The tubular beam butt joint structure is connected by arranging an inner liner and an outer liner, the size and the material of the inner liner and the outer liner are determined firstly so as to ensure that the butt joint structure has enough impact resistance, a liner machining mold is designed firstly, and the inner liner machining mold and the outer liner machining mold are matched; a lining is manufactured; then an outer lining machining mold is designed, the outer lining is manufactured, the forming precision of the inner lining and the outer lining is guaranteed, the assembly requirement can be met, then the outer side tubular beam, the inner lining, the outer lining and the inner side tubular beam are sequentially connected, the wing ribs are finally fixed, the structure is simple, the preparation process is simple, the assembly process is simplified, and the production cost is reduced. And the weight optimization is realized while the structural function is completed.

    本申请属于无人机结构设计领域,为一种带锥度管梁对接结构设计及制备方法,通过设置内衬和外衬来进行管梁对接结构的连接,通过先确定内衬和外衬的尺寸和材质,以保证对接结构有足够的抗冲击性能,先设计内衬加工模具,并制造内衬;而后设计外衬加工模具,并制造外衬,保证内衬与外衬的成型精度,以能够满足装配需求,而后通过通过依次连接外侧管梁、内衬、外衬和内侧管梁,最后固定翼肋,结构简洁、制备工艺简单,简化了装配工艺,在完成结构功能的同时实现了重量的优化。
