Abstract

Abstract

Circular arc indentations were introduced into metal thin-walled cylinders.And a multi-objective optimization model was built by taking the number and the radius of the indentations as optimization parameters, as well as the specific energy absorption and the crushing force efficiency as evaluation indexes.The effects of the circular arc indentations introduced with uniform intervals were analyzed on the structural energy absorption, the maximum crushing force and the smoothness of the crushing force curve.The collision responses of different geometrical models were obtained by using the finite element software LS-DYNA.The objective functions were constructed based on the radial basis function.The multi-objective optimization for the thin-walled cylinders with the induced indentations was presented by using the ideal point method.The number and the radius of the optimal indentations were obtained.So the optimization design was achieved for the ideal indentations.
