摘　　要：为进一步提高玻璃钢管道性能并降低成本,设计了一种新型玻璃钢空心夹层管道结构及其制作工艺。与传统玻璃钢管道相比,在同等环刚度条件下,玻璃钢空心夹层管道具有重量轻、成本低、抗冲击性能好等优势。采用材料力学及复合材料相关理论分析了空心夹层管道的强度和环刚度,采用欧拉公式分析了芯材的稳定性。同时采用ANSYS软件分别建立了管环和胞单元的有限元模型,对空心夹层管道的强度、环刚度以及芯材的稳定性进行了分析。对比理论计算结果和有限元分析结果,两者基本一致,验证了强度、环刚度和稳定性的理论计算方法的可靠性。In order to further improve the performance of FRP pipe and reduce the cost,fiberglass hollow sandwich pipe was designed.Compared with traditional fiberglass pipe,the new fiberglass hollow sandwich pipe has many advantages,such as light weight,low cost,and good impact resistance under the same ring stiffness.The strength and ring stiffness of the hollow sandwich pipe were analyzed using the theory of mechanics of materials and composite materials.The Euler formula was used to analyze the stability of the core material.At the same time,ANSYS software was used to establish the finite element model of the pipe ring and cell unit,and the strength,ring stiffness and core material stability of the pipe were analyzed.The results of the theoretical calculation and the finite element analysis are in close agreement,which verify the reliability of the theoretical calculation methods of strength,ring stiffness and stability.
