| 中文摘要: |
| 为研究具有密闭结构的装备、 建筑物或地下工事在内爆炸载荷作用下的冲击振动响应， 通过某一尺寸爆炸容器的冲击振动环境试验构建内爆炸振源模型和密闭结构响应模型， 比较测量了几个典型位置在不同强度载荷下的振动情况并进行频谱分析， 提出了基于振动主频的判断结构损伤和防止共振响应的方法， 并对试验数据进行数值拟合， 弄清振动参数在结构上的衰减规律， 为密闭结构的安全使用和设计改进提供依据。 |
| 英文摘要: |
| 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. |
