摘要
为了提高有限元方程的求解计算速度,本文研究了三种有限单元的划分方法并进行了比较。结果表明正方化四边形单元划分方法的收敛平稳,需要划分的份数少,计算量小,而且收敛快,这为进一步研究回转圆盘零件的横向振动及提高其稳定性奠定了基础。
This paper studies three partition methods of the finite element,for improving computation speed of the finite element equation.The results shows constringency placidity of the square fan-shaped grid division method,with few partition,few computation and rapid constringency.This result will lay the foundation for further research of the disk part lateral vibration and increase its stability.
