Abstract

The invention relates to a nonlinear elastic shock absorption bed board which comprises a bottom plate. T-shaped steel arranged vertically and transversely at intervals is welded to the upper surfaceof the bottom plate. The upper surfaces of the T-shaped steel are located at the same plane position. Multiple supporting spring piece assemblies are evenly distributed on the upper surfaces of the T-shaped steel at intervals, and a face plate is installed at the upper portions of the supporting spring piece assemblies through fasteners. A double-layer plate structure form is adopted, the T-shapedsteel is installed on the bottom plate to serve as a reinforced flat plate, the face plate is a single-layer flat plate, and nonlinear euler spring pieces are adopted in the middle for connecting andsupporting. In order to ensure the bearing performance of a bed board structure, the face plate can be subjected to strengthening treatment in a thickening manner or a reinforcing manner or other manners so that the bearing capability of the face plate can be improved, and stress deformation of the face plate is reduced.

Description

technical field [0001] The invention relates to the technical field of vibration-damping equipment, in particular to a non-linear elastic vibration-damping plank. Background technique [0002] In order to efficiently use the limited internal space, most cabins of conventional submarines are arranged with 1-2 layers of planks (platforms), and nuclear submarines are arranged with 3-4 layers of planks (platforms). In addition to the function of separating various functional areas, decking can also provide installation and support platforms for many equipment and piping systems. Most of the planks commonly used in engineering practice are flat-plate reinforced structures, and the two sides are rigidly connected to the hull by direct welding. The transverse ribs under the planks are also rigidly connected to the pressure hull through brackets. The decking is excited by the vibration of the upper equipment to generate bending waves and longitudinal waves, which are then reflected...
