Optimum Design of Buried Heating Elbow based on Genetic Algorithm
摘要
Abstract
The design process of elbow of the direct-burying heating pipeline is one kind of pilot calculation process, namely assigns parameters as radius of curvature and pipe wall thickness to carry on the stress checking calculation, until stress checking calculation is qualified. In this article the radius of curvature, pipe wall thickness and intensity condition were used as the constraints, and the lowest cost of elbow were used as the objective function, to conduct the optimization design of elbow. Through optimized computation of pipelines with different specifications below DN1000mm, the optimal radius of curvature and pipe wall thickness were obtained for thehorizontal elbow with two infinite long arms. The genetic algorithm can be used to carry out the optimum design for the elbow. The problems of misalignment restraint, can be dealt with by u-sing the SUMT to reach stably consistemt convergence and fast convergence rate. The application of the genetic algorithm to the engineering design computation of elbow of the direct-burying heating pipeline can realize optimized design no matter whether the elbow size is restricted by location. The arrangement flexibility and reliability of the elbow can be improved and the project investment can be reduced.关键词
