The Optimization Design of Laser Welded Sandwich Plate Structure

Abstract:

Height lightweight is one of key technology to dock structure that is made up of the sandwich composite board and satisfy requirements of bending rigidity feature. This paper proposes a new engineering optimization method which is both precision and economical. First, through theoretical calculation, to get bending stiffness( , ) and twist stiffness( ). Afterwards ,based on structures bending theory ,we could get the stiffness equation of the model , and calculate the quality equation of the model equations. Supposed the maximal stiffness as objective function ,height(h) of rib and space of rib(a) as design variable.Using MATLAB software and ABAQUS finite element software, we could get the Optimized design program that is to meet the requirements of the structural characteristics of sandwich composite panels of the dock structure. In 100 tons load, when the length of plate is 1m, thickness of plate is 4mm, the height of the rib is 40 mm, the spacing of the rib is 75 mm, and when the height is 45 mm, the spacing is 95 mm, the bending performance of the whole mode lis betterand the quality is more lighter.
