| Abstract: |
| The explosion vibration source model and its response model of closed structure were established through environmental test to investigate the vibration response of equipment, construction and fortification with closed structure under internal explosion loading. The vibrations on several typical positions were measured and their frequency characteristics were analyzed. The method of determining structural damage and preventing resonance response were proposed based on dominant frequency. The experimental data were fitted to establish vibration response law and empirical formula. The purpose was to reference for safe application, design, and improvement of closed structure. |
