The invention discloses an efficient vibration reduction raft frame based on an L-shaped continuation type structure. The raft frame comprises a raft frame panel, a raft frame bottom plate, a plurality of raft frame longitudinal rib plates and a plurality of raft frame transverse rib plates, wherein the raft frame panel and the raft frame bottom plate are oppositely arranged, and a plurality of raft frame longitudinal rib plates and a plurality of raft frame transverse rib plates are respectively transversely and longitudinally arranged to jointly form a plurality of cell structures; at least one L-shaped continuation type structure is arranged in the raft frame transverse rib plate and/or the raft frame longitudinal rib plate, the L-shaped continuation type structure comprises a first connecting plate and a second connecting plate perpendicular to the first connecting plate, an upper end of the first connecting plate is connected with the raft frame transverse rib plate and/or the raft frame longitudinal rib plate, and a lower end of the second connecting plate is connected with the raft frame transverse rib plate and/or the raft frame longitudinal rib plate. According to the efficient vibration reduction raft frame based on the L-shaped continuation type structure, waveform conversion, scattering and reflection of vibration waves in the base are increased, the transfer impedance of the raft frame can be improved, and then the vibration isolation effect of a vibration isolation system is improved.
本发明公开了一种基于L型延拓型结构的高效减振筏架,包括相对设置的筏架面板和筏架底板、以及筏架纵肋板和筏架横肋板,筏架横肋板和筏架纵肋板分别横向和纵向设置多根以共同形成多个单元格结构,筏架横肋板和/或筏架纵肋板的内部设置有至少一个L型延拓型结构,L型延拓型结构包括第一连接板以及与其垂直的第二连接板,第一连接板的上端与筏架横肋板和/或筏架纵肋板连接,第二连接板的下端与筏架横肋板和/或筏架纵肋板连接。本发明提出的基于L型延拓型结构的高效减振筏架,增大了振动波在基座中的波形转换、散射和反射,可提高筏架的传递阻抗,进而提高隔振系统的隔振效果。
