The shock response caused by transient vibration often becomes a problem in various vehicles. In this study, the countermeasure for shock response of thin plate structure was designed by optimized calculation. The optimized calculation was conducted by topology optimization and size optimization. The topology optimization was conducted based on frequency response analysis. The result indicated that the maximum value of shock response spectrum (SRS) reduced by 73.5% compared with typical double cross rib configuration. The size optimization was conducted for abstracted model from result of topology optimization based on transient analysis. Finally, the optimized rib structure showed that the maximum value of SRS reduced by 52.7%.
