Optimal Design for the Shape and Size of Can?
Abstract: For the decreasing in the weight of a can and the increasing in the avail of material and the reducing in the cost of production, the optimal design for the shape and size of can is present in this paper. Firstly, the optimum design for the cylinder can is present by according to its measuring data and the demands of mathematical modeling. Secondly, the optimum design for the can of circular truncated top and columnar bottom is also present. Finally, the optimal design for the shape and size of can is proposed, and the super……
