摘要：研究了不同有限元计算方法对轴对称物体计算精度影响的问题,从理论上对比分析了平面应力、轴对称、三维立体分析的异同。此外,分别应用平面应力、轴对称、三维立体有限元法对轴对称物体进行了有限元分析,并对三种算法及不同单元密度得到的径向应力、周向应力、等效应力进行了对比分析。
The effect of different finite element methods for axisymmetric objects to the calculating accuracy was studied.The theoretical comparative analysis of the plane stress,axisymmetric,three-dimensional analysis was done.Moreover,plane stress,axisymmetric and three-dimensional finite element analyses were done.The radial stress,circumferential stress and equivalent stress with three kinds of analysis methods and different element densities were compared and analyzed.
