摘要/Abstract

摘要： 玻璃钢夹砂管道性能优良,常被用作地下管道,但许多国家因其造价相对于传统埋地管道较高而不予采用。以管道环刚度为参考指标,对DN1500玻璃钢夹砂管进行优化设计,旨在降低管道成本。首先,对DN1500管道环刚度进行试验测试,运用ANSYS对管道环刚度进行模拟计算;将实验数据与模拟数据进行对比,验证了ANSYS分析管道环刚度的可行性。其次,运用ANSYS分析管道层数、纤维体积比、交叉缠绕层体积比、纤维缠绕角度等参数和环刚度的关系,得到环刚度与四种变量的关系。最后,利用MATLAB与ANSYS联合仿真技术,结合PSO智能算法对管道结构进行优化;优化后的管道满足环刚度的要求,同时体积相对于原管道减少了12%。

Abstract: The glass fiber reinforced plastic mortar sand pipe has high performance and is often used as the underground pipe. However, many countries do not adopt the glass fiber reinforced plastic sand pipe because of its higher cost compared to that of the traditional buried pipe. This paper takes the pipe ring stiffness as a reference index to optimize the design of the DN1500 glass fiber reinforced plastic sand pipe, aiming to reduce the piping cost. Firstly, this paper tests the ring stiffness of DN1500 pipe and then simulates the pipe ring stiffness of with ANSYS. The experimental data and simulation data are compared to verify the feasibility of ANSYS in analyzing the pipe ring stiffness. Secondly, ANSYS was used to analyze the relationship between the ring stiffness and the four variables, such as the pipe layer number, the fiber volume fraction, the intercross enwind layer volume fraction and the fiber winding angle, thus obtaining the relationship between the ring stiffness and the four variables. At last, this paper uses the MATLAB and ANSYS joint-analysis and combines with the PSO intelligence algorithm to optimize the pipe structure. The optimized pipe not only meets the requirement of ring stiffness, meanwhile, its volume is 12% less than that of the original pipe.
