摘要:
摘要:对于高密度聚乙烯管道的连接,焊接技术是直接影响高密度工程塑料压力管道安全应 用的关键环节。而焊接过程中的温度场分布对焊接质量又有十分重要的影响。通过MARC软件 建立了聚乙烯管道焊接接头一维非稳态整体传热模型,模拟焊接过程中的温度场及应力场分布,并 通过热电偶温度自动采集系统对焊接时的温度场变化进行检测,并通过模拟结果与实验进行对比。 结果表明,在加热结束时,管件端面温度并没有达到最大值,而是在300 s时达到最大值,这表明了 在压焊过程中发生了相变潜热。在压焊过程中,管件轴向应力由拉应力逐渐过渡到压应力。
Abstract:
Abstract:For high density polyethylene pipe connection,welding technology is the key of the high density engineering plastic pressure pipe safety. And the temperature distribution in the welding process has a very important influence on the welding quality. Polyethylene pipe weld joints of one dimensional unsteady overall heat transfer model is established by MARC software and simulates temperature field and stress field distribution of the welding process,and the thermocouple temperature automatic acquisition system of welding temperature field changes were detected,and compared by simulation and experiment .The results show that,at the end of the heating,the temperature of the pipe does not reach the maximum,but reached the maximum at 300 s,which indicates that the latent heat of phase change in the process of pressure welding. In the process of pressure welding, the axial stress of the pipe is gradually changed from tensile stress to compressive stress.
