The invention discloses a box-type main engine back shore reinforcing structure which comprises a reinforcing longitudinal partition plates, a reinforcing transverse partition plates and reinforcing bottom plate which are arranged under a lower platform of an engine room. The longitudinal reinforcing partition plates and the transverse reinforcing partition plates are perpendicularly and fixedly arranged at the bottom of the cabin lower platform. The reinforcing transverse partition plates are perpendicular to the reinforcing longitudinal partition plates. The reinforcing bottom plate is simultaneously and fixedly arranged at the bottoms of the reinforcing longitudinal partition plates and the bottoms of the reinforcing transverse partition plates; the number of the reinforcing longitudinal partition plates and the number of the reinforcing transverse partition plates are multiple. The reinforcing longitudinal partition plates are parallel to each other; the reinforcing transverse partition plates are parallel to each other; a plurality of hollow cuboid structures are defined by the cabin lower platform, the reinforcing longitudinal partition plates, the reinforcing transverse partition plates and the reinforcing bottom plate. A main engine back shore is perpendicularly arranged on the reinforcing longitudinal partition plate in the outermost side, and the central axis of the main engine back shore coincides with one reinforcing transverse partition plate. The rigidity of the structure near the main engine back shore is improved, the ship vibration response level caused bymain engine vibration is obviously reduced, and therefore the ship comfort is improved.
本发明公开了一种箱型主机顶撑加强结构,其包括设于机舱下平台的下方的加强纵隔板、加强横隔板和加强底板;加强纵隔板和加强横隔板均垂直固设于机舱下平台的底部;加强横隔板垂直于加强纵隔板;加强底板同时固设于加强纵隔板的底部和加强横隔板的底部;加强纵隔板和加强横隔板均为多个;加强纵隔板之间相互平行;加强横隔板之间相互平行;机舱下平台、加强纵隔板、加强横隔板和加强底板围成多个中空的长方体结构;主机顶撑垂直设于最外侧的加强纵隔板上,主机顶撑的中轴线与一个加强横隔板重合。本发明增加了主机顶撑附近结构的刚度,明显降低由于主机振动引起的船舶振动响应水平,从而提高了船舶舒适性。
