Optimum Design Study of Hydraulic Hatch Cover on Buckling Strength

Abstract:

The hydraulic hatch cover is used to seal rainwater and to carry container and weather loads. The method of optimization theory based on dual method has been transplanted to optimize hatch cover structure in the present paper, and the numerical calculation model of hatch cover structure was established. The target function is the structure gravity of hatch cover, there are three kinds of constraints: yielding strength, rigidity and buckling strength. The hydraulic hatch cover has been optimized under multiple loads, the numerical calculation results meet the design requirements.
