浅析爆破试验台压力容器

通过压力容器失稳和爆破试验，可以检查压力容器的各项机械性能、结构设计的合理性与可靠性，以及实际安全裕度的大小和其它方面性能。因此，在爆破试验台教学实验中需要Through the pressure vessel destabilization and blasting test, can check the rationality and reliability design of the mechanical properties, structure of pressure vessels, as well as the actual safety margin size and other aspects of the performance. Therefore, in the blasting test-bed experiment in Teaching (l)测定试验容器在整个爆破过程的“压力—膨胀量”关系曲线;(L) test container in the blasting process "pressure expansion curve" relationship; (2)测定试验容器爆破压力。(2) determination of bursting pressure. 在容器爆破断裂口完好的情况下根据测定的数据、实验现象，对断口形貌进行分析，做出爆破实验结果评定。在失稳教学试验中需要In container blasting fracture well under the circumstances according to the measured data, the experimental phenomena, the fracture morphology analysis, make the blasting results evaluation. Need to instability in the teaching experiment. （1）观察外压容器的失稳破坏现象及破坏后的形态，分析变形和破坏的实质。(1) to observe the external pressure vessel failure phenomena and failure mode, the substantive analysis of deformation and failure of the. （2）验证外压筒体试件失稳时临界压力的理论计算式，分析轴向力对失稳的影响。(2) calculation of cylinder specimen buckling critical pressure test pressure theory, analysis of axial force influence on instability. 为了能在教学环境下实现压力容器失稳和爆破试验台http://www.xinmingte.com/的教学效果，使每个学生都能理解试验理论、掌握压力容器爆破和失稳的实验操作，许多高校和实验研发单位都进行过实验装置开发。但成本较高，效果较差，为弥补现有实验不足，因此产生了基于“网络化虚拟技术”开发“压力容器的爆破与失稳实验”的想法。In order to realize the pressure vessel in the teaching environment of instability and blasting test-bed teaching effect, so that each student can understand the test theory, master the pressure vessel explosion and loss of the experimental operation stability, many universities and research units have been developing experiment device. But the high cost, poor effect, to make up for the deficiency of existing experiments, which is based on the "virtual technology" development "pressure vessel explosion and instability experiment".
