| 摘 要： | 通过优化组合参数近似实现零能误差的方法,分别对8参数能量协调轴对称元和完全线性应力插值的轴对称元进行了优化.数值算例结果表明,能量协调轴对称元具有高精度、不发生PoissonLocking和对网格畸变不敏感的特点;经过优化之后的轴对称元性能能够得到进一步改善. |
| 关 键 词： | 组合杂交元 轴对称 零能误差 能量协调 参数优化 |

| Abstract: | Zero energy-error is used to optimize combined hybrid axisymmetric finite elements though adjusting the combined factor.These axisymmetric finite elements include eight-parameter energy compatibility axisymmetric finite element and complete linear stress interpolation axisymmetric finite element.Numerical results all indicate that energy compatibility axisymmetric finite element exhibits better numerical precision,excellent performance at the nearly incompressible limit and distortions of the element geometry,and element performances are improved after optimization. |
| Keywords: | combined hybrid method axisymmetric zero energyerror energy compatibility parameter optimization |
