摘要：

针对高温管道系统热应力分析中传统有限元方法刚度过硬导致的计算精度差问题,提出单元基光滑点插值法（CS-PIM）引入热应力分析中.该方法采用易于剖分的三角形/四面体背景网格,在单元基础上进行梯度光滑,用点插值法构造形函数.通过二维及三维的算例验证,结果表明，在计算高温管道温度时,基于相同网格的单元基光滑点插值法和传统有限元法的结果收敛率相当,但前者可以取得更高的精度|结果表明，在计算热应力结果时,得益于单元基光滑点插值法可以有效软化模型刚度,计算结果的精度和收敛率都明显高于传统有限元方法.
Abstract:

The cell-based smoothed point interpolation method (CS-PIM) was applied for thermoelastic problems in high temperature pipe system, for which a finite element method (FEM) model generally results in bad accuracy due to the natural overlystiff property. In the scheme of CS-PIM, the computational domain was discretized into triangular/tetrahedron background cells, Then the generalized gradient smoothing operation was conducted upon the cells and shape functions were constructed using the point interpolation method. Both 2D and 3D cases study were conducted .The CS-PIM can obtain similar convergence rate but better accuracy for temperature results than the FEM does with the same mesh. For thermal stress analysis, the method achieves better results about both accuracy and convergence than the traditional FEM owing to the effectively softened stiffness.
