Abstract： To enhance the warship vitality, the double-bulkhead was set on the latest Europe warship. Numerical simulation method was adopted to study the structure response of ordinary double-bulkhead module under internal explosion. The blast wave propagations in the cabin, the impact loads on the bulkhead and structure plastic responses were discussed. The double-bulkhead damage pattern under internal explosion was researched. Corresponding to this pattern, the anti-explosion design of double-bulkhead was discussed preliminarily and the improved design plan is proposed. The bulkhead corner plate thickness was increased and longitudinal bulkheads were added between two bulkheads. Through the analysis, the improved double-bulkhead design plan can effectively increase the anti-internal-explosion capability.
