Polymer pipes are used in the construction of underground gas, water, and sewage networks. During exploitation, various external forces work on the pipeline, which cause its deformation. In the paper, numerical analysis and experimental investigations of polyethylene pipe deformation at different external load values (500, 1000, 1500, and 2000 N) were performed. The authors measured strains of the lower and upper surface of the pipe during its loading moment using resistance strain gauges, which were located on the pipe at equal intervals. The results obtained from computer simulation and experimental studies were comparable. An innovative element of the research presented in the article is recognition of the impact of the proposed values of the load of polyethylene pipe on the change in its deformation.
聚合物管道用于地下燃气、水和污水网络的建设。在使用过程中,管道会受到各种外力作用,从而导致其变形。本文对不同外部载荷值(500、1000、1500和2000 N)下聚乙烯管道的变形进行了数值分析和实验研究。作者在管道加载过程中,使用电阻应变片等间隔地测量了管道上下表面的应变。计算机模拟和实验研究得到的结果具有可比性。本文研究的一个创新点是认识到所提出的聚乙烯管道载荷值对其变形变化的影响。
