Aero-engine lubricating oil tank support and design method thereof

The invention provides an aero-engine lubricating oil tank support and a design method thereof, and belongs to the field of aerospace support structures. The support for the lubricating oil tank of the aero-engine is of an integral structure. The support for the lubricating oil tank of the aero-engine comprises a plurality of lugs and connecting structures connected between the adjacent lugs, and the connecting structures are provided with hollows; and each lug is provided with a through hole. Compared with a traditional support structure, the overall rigidity of the support structure and the local rigidity of the connecting positions of the lug pieces are obviously improved, the stress distribution of the strap structure connected with the support structure can be improved through improvement of the local rigidity of the connecting positions of the lug pieces, the strap structure does not bear eccentric tension any more, and the stress level of the strap structure is reduced. 本发明提供了一种航空发动机滑油箱支架及其设计方法，属于航空航天支
