【摘要】：随着工业的迅猛发展，国家的日益强盛，多层爆炸容器在工业、公共安全、实验等领域起到的作用越来越重要。由于爆炸容器所受冲击载荷作用下，所产生动力响应的复杂性，至今对爆炸容器在爆炸作用下的动力特性的研究成果比较少。文中选取扁平与型槽绕带式两种爆炸容器作为结构模型，并且对这两种爆炸容器在其内部爆炸载荷作用下的动力特性进行研究与比较。文中给出了扁平绕带式爆炸容器在内部爆炸载荷作用下的理论分析和数值模拟，并与实验数据相对比。给出了型槽绕带式爆炸容器在内部载荷作用下的数值模拟，并通过改变结构模型，给出了不同的结构因素对容器抗爆性的影响。同时，在同等耗材的情况下，对比扁平与型槽绕带式爆炸容器的抗爆性能，得出以下结论：1.所建立的数值模拟的有限元模型和理论分析的数学模型是非常可靠的。2.扁平绕带式爆炸容器绕带层的倾角越小，其容器的抗爆性能越大。3.齿槽为矩形的型槽绕带式爆炸容器比齿槽为三角形的和齿槽为梯形的型槽绕带式爆炸容器的抗爆性能要好。4.在一定范围内，，型槽绕带式爆容器的锯齿的长度越长，其容器的抗爆性能越好。5.型槽绕带式爆炸容器内腔的轴向长度越长，其容器的抗爆性能越好。6.扁平绕带式爆炸容器的抗爆特性比型槽绕带式爆炸容器的抗爆特性要差。
[Abstract]:With the rapid development of industry and the growing prosperity of the country, the multi-layer explosive container plays an increasingly important role in the fields of industry, public safety, experiment and so on. Because of the complexity of the dynamic response, there are few research results on the dynamic characteristics of explosive vessel under explosion. In this paper, two types of explosive vessels, flat and groove-wound, are selected as the structural model. The dynamic characteristics of the two explosive vessels under the action of internal explosion load are studied and compared. In this paper, the theoretical analysis and numerical simulation of flat-wound explosive vessel under the action of internal explosion load are given. Compared with the experimental data, the numerical simulation of the shaped groove-wound explosive vessel under internal load is given, and by changing the structural model, the influence of different structural factors on the anti-explosion performance of the vessel is given. In the case of the same consumables, the anti-explosion performance of flat and grooved wound explosive vessels is compared. The following conclusions are drawn: 1. The finite element model of numerical simulation and the mathematical model of theoretical analysis are very reliable. The bigger the anti-explosion performance of the vessel is. 3. The anti-explosion performance of the shaped groove-wound explosive vessel with rectangular groove is better than that with triangular groove and trapezoidal groove. 4. Within a certain range. The longer the sawtooth length of the zigzag vessel, the better the anti-explosion performance of the vessel. 5. The axial length of the inner cavity of the zigzag explosive vessel is longer. The better the anti-explosion performance of the vessel is. 6. The anti-explosion characteristic of the flat wound explosive vessel is worse than that of the type groove wound explosive vessel.
