The invention relates to the field of engine mounting brackets, and discloses an aero-engine cabin mounting structure, which comprises a spliced bracket, a middle fixing piece; the middle end vibration absorption mechanism comprises a torsional vibration buffering mechanism fixedly connected to the middle fixing piece and a plurality of three-way comprehensive vibration buffering mechanisms connected to the torsional vibration buffering mechanism, and the other ends of the three-way comprehensive vibration buffering mechanisms are connected with the parallel connecting parts correspondingly; the three-way comprehensive vibration buffering mechanism is used for offsetting three-way comprehensive vibration transmitted from the parallel connecting part; the installation support, the fixing end and the supporting end are detachably connected, meanwhile, the middle end vibration absorption mechanism is used in an auxiliary mode, vibration generated by different parts of an engine can be absorbed in a self-adaptive mode, in daily use, when the local damage degree is large, the replacement number of assemblies is reduced, the maintenance cost can be effectively reduced, and the overall vibration absorption effect is good.
本发明涉及发动机安装支架领域,公开了一种航空发动机座舱安装结构,包括:拼接式支架;中部固定件;中端吸振机构,所述中端吸振机构包括固定连接在中部固定件上的扭曲振动缓冲机构以及连接在扭曲振动缓冲机构上的若干个三向综合振动缓冲机构,若干个所述三向综合振动缓冲机构的另一端分别与若干个平行连接部连接,所述三向综合振动缓冲机构用于抵消从平行连接部处传递的三向综合振动;本发明的安装支架,固定端和支撑端采用可拆卸式连接,同时辅以中端吸振机构,可以自适应吸收发动机不同部位所产生的振动,并在日常使用中,出现局部受损程度较大时,减少组件的更换数量,可有效的降低维修成本,整体的吸振效果较佳。
