The invention belongs to the field of aero-engine design, and relates to a perforated silencing plate layering structure which comprises a transverse layering part and a longitudinal layering part, the transverse layering part and the longitudinal layering part are integrally arranged, the transverse layering part comprises first transverse plates and first longitudinal plates, and the multiple sets of first transverse plates and first longitudinal plates form an S-shaped structure; the longitudinal laying piece comprises second transverse plates and second longitudinal plates, and the multiple sets of second transverse plates and second longitudinal plates form an S-shaped structure. According to the invention, the transverse laying piece and the longitudinal laying piece which are integrally arranged are arranged, the transverse laying piece and the longitudinal laying piece are mutually crossed in structure to form a spatial itinerant structure, and a three-dimensional bearing structure is formed through integral repeated overlapping, so that the overall and local fatigue resistance is improved; when the noise reduction plate is used, the transverse laying piece and the longitudinal laying piece can be stressed at the same time for loads in any direction, so that the loads are dispersed to all positions of the noise reduction plate, interlayer stripping is prevented, meanwhile, the overall performance is improved, and the load resistance and the deformation resistance are greatly improved.
本申请属于航空发动机设计领域,为一种穿孔消音板铺层结构,包括横向铺层件和纵向铺层件,横向铺层件与纵向铺层件一体设置,横向铺层件包括第一横板和第一纵板,多组第一横板和第一纵板形成S形结构,纵向铺层件包括第二横板和第二纵板,多组第二横板和第二纵板形成S形结构;通过设置一体设置的横向铺层件和纵向铺层件,并且横向铺层件与纵向铺层件在结构上相互交叉,形成空间巡回结构,通过一体的反复交叠形成三维承力结构,从而提高整体和局部的抗疲劳性;面对任意方向的载荷,横向铺层件和纵向铺层件会同时受力,从而将载荷分散至消音板的各个位置,在防止层间剥离的同时,整体性能提高,抗载荷、抗变形能力大幅提高。
