摘要:

针对腐蚀管道的剩余强度预测中公式计算准确性较低和有限元分析（FEA）过于繁琐的问题，提出了一种改进的粒子群算法优化的神经网络模型（IPSO-BPNN）来预测腐蚀管道剩余强度。首先，在传统粒子群算法的基础上，提出了一种双向递减惯性权重，引入了遗传交叉算子，形成了改进的粒子群算法（IPSO）。其次，采用IPSO算法对神经网络的权重和阈值进行优化，建立IPSO-BPNN模型。最后，在真实的管道测试爆破数据集上进行实验，分别使用线性回归(LR)、FEA、BPNN、PSO-BPNN以及IPSO-BPNN模型对腐蚀管道剩余强度进行预测。结果表明，IPSO-BPNN模型的预测精度较LR、FE、BPNN和PSO-BPNN有明显提升。

Abstract:

Due to the impact of buried environment and medium transported, oil pipelines will be gradually corroded with the increasing of service life. Traditional methods for calculating the residual strength of corroded pipelines included formula calculation and finite element analysis, etc. Aiming at the problems of low calculation accuracy of formulas and too complicated finite element analysis (FEA) in the prediction of the residual strength of corroded pipelines, an improved particle swarm optimization neural network model (IPSO-BPNN) was proposed to predict the residual strength of corroded pipelines. Firstly, based on the traditional particle swarm optimization, a new nonlinear decreasing inertia weight was proposed to update the velocity and location of elements quickly, and the genetic crossover operator was introduced to increase the diversity of particles, then form an improved particle swarm optimization algorithm (IPSO). Secondly, the IPSO algorithm was used to optimize the weights and thresholds of the neural network, and initialize the neural network with optimized weights and thresholds to establish the IPSO-BPNN model. Finally, the linear regression(LR),FEA, back-propagation neural network(BPNN), particle swarm optimization back-propagation neural network(PSO-BPNN) and IPSO-BPNN model were experimented on real pipelines test blasting data sets to predict the residual strength of the corroded pipelines. MAE, RMSE and MAPE were used as indicators to evaluate the predic-tability of the models. The results on the test set of two data sets showed that the MAE of the IPSO-BPNN model was 0.525 4, 0.718 5; the MAPE was 3.77%, 2.68%; the RMSE was 0.672 6, 0.947 2, respectively. The three indicators were significantly improved compared to LR, FEA, BPNN and PSO-BPNN. It showed that this method could improve the accuracy of predicting the residual strength of corroded pipelines, and could provide a more accurate basis for pipeline inspection.
