Abstract

In a vehicle design which realizes good crash properties, it is desirable to increase the maximum and the mean crash load of a vehicle structure. A sensitivity analysis may be used to examine a vehicle structure efficiently. However, no report regarding this usage has been presented because of the complex nature of a vehicle crash analysis. In this paper, a new method for a sensitivity analysis is presented, which deals directly with a buckling load. As this is the first report, sensitivity of a structure is investigated to increase dynamic buckling strength, where the dynamic buckling is regarded as higher-order static buckling with a mode similar to the dynamic mode. A new approach to dynamic buckling problems based on a study of dynamic properties is introduced and discussed.
