Abstract基于热粘弹性积分型本构关系,考虑材料性能依赖于温度变化及相变潜热的影响,利用AN SYS热-力耦合及载荷步功能模拟结晶型高密度聚乙烯(HDPE)塑料压力管道热板焊接过程,并对焊接接头的应力分布进行有限元分析,得到了环向、轴向以及径向瞬态应力分布的基本规律。采用盲孔法和锯切法测量焊后残余应力,实测结果与数值分析基本符合
Other AbstractBased on constitutive relationship of thermal viscoelastic integral-mode and the properties of material, which depend on temperature fluctuation and the effect of phase-transition latent heat, heat-force coupling function and load step character of ANSYS were employed to simulate the hot-plate welding procedure of high-density polyethylene (HDPE) plastic pressure pipe. The finite-element analyses on stresses distribution of welded joint was conducted, and transient stresses distribution pattern in axial, radial, and circumferential directions were obtained. Residual stresses was measured by blind hole drilling method and the cutting method, it proved that the actual measuring results of the residual stresses are basically coincident with the results of numerical analysis.
