Drill ship transportation track based on frequency domain dynamic response optimizes improvement structure

Drill ship transportation track based on frequency domain dynamic response optimizes improvement structure, the base of the rail of the fixed bar of longeron top surface, the parallel fixed slide rail of base of the rail upper portion colleague, base of the rail width with highly all be lighter than the slide rail, wherein, the fixed axle sleeve of embedding on the wall of longeron side, installation extension board in longeron bottom is at the end of longeron one end upside slide rail along the spacing fender of external fixation. Can react the response of this track structure in the wave through the frequency domain analysis method comprehensively, under the intensity condition furthest utilize the material, according to the accurate design transportation track structure of frequency domain analysis research, the structure is firm, the dynamic stress of authentic and valid response boats and ships in the wave, can the accuracy control rail warp and says that improve transportation safety, economy is applicable, prolongs structural life-time simultaneously.
