In a vehicle design to realize good crash properties, it is desired 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 complex nature of a vehicle crash analysis. In this paper, a new method for a sensitivity analysis is presented, which deals with a bucking load directly. As the first report, sensitivity of a structure to increase dynamic buckling strength is investigated, where the dynamic buckling is regarded as higher order static bucking whose mode is similar to the dynamic mode. A new approach to dynamic buckling problems based on a study of dynamic properties is introduced and discussed.
