【摘要】：对玻璃纤维增强复合软管进行短期爆破压力试验,建立内压载荷下玻纤软管有限元模型进行模拟仿真计算,在此基础上,研究提出了玻纤软管爆破压力的理论求解方法。将三者进行对比分析,结果表明:在一定内压作用下,加强层所受到的力远大于内外层,说明了玻纤软管的加强层承担大部分内压载荷;玻纤缠绕角度大于45°且小于80°时,抗内压能力逐渐增强,59°为玻纤软管设计中最优缠绕角度;适当减小管道的径厚比,可以提高管道承受内压的能力。
[Abstract]:The short term blasting pressure test of glass fiber reinforced composite hose was carried out and the finite element model of glass fiber hose under internal pressure was simulated. On this basis, the theoretical solution method of blasting pressure of glass fiber hose was put forward. The comparison and analysis of the three cases were carried out. The results showed that under certain internal pressure, the reinforced layer was subjected to a certain pressure. The force is far greater than the inner and outer layers, indicating that the reinforced layer of the glass fiber hose bears most of the internal pressure load; when the angle of the glass fiber is greater than 45 degrees and less than 80 degrees, the resistance to internal pressure is increased gradually, and the 59 degree is the optimal winding angle in the design of the glass fiber hose, and the proper reduction of the diameter to thickness ratio of the pipe can improve the capacity of the pipeline to withstand the internal pressure.
