Abstract

We have developed many types of transport boxes by origami-operation and space filling operation. But it has not been solved that the fruits, vegetables, strawberries, cells, blood and a bottle of liquor are damaged, broken during transportation. It is the greatest factor in this situation that there is a danger vibration frequency band where these are easy to scratch and are prone to death. If there are eigen frequencies within this danger frequency band, it needs that those eigen frequencies within this danger frequency band are moved out of the band. But it is difficult to apply the existing topology optimization methods using homogenization method or density method to control plural eigen frequencies for two reasons. One reason is that even if homogenization method or density method is used, finally after convergence, holes are made on finite elements of which the size of the homogenizing element or the thickness is smaller than the threshold by keeping the rest the original size. In such processing, there is a possibility that the converged solution again deviates from the convergence value. Another reason is that it is difficult to control plural eigen frequencies simultaneously because some eigen frequencies go up and some ones go down no matter where it is reinforced although displacement at any point goes down in static problem. Although in such way, it is very difficult to control plural eigen frequencies, here we propose a new high precision and high efficiency method for controlling plural eigen frequencies simultaneously using the kinetic energy density and the strain energy density.
