| 中文摘要: |
| 提出分块波前法求解非对称大型有限元方程组，该方法综合分块解法和波前法的优点，根据计算机容量和方程的阶数优化计算过程，以在经济效率和存储效率之间达到平衡。本文利用该方法求解了轮胎稳态滚动有限元方程组，表明该方法是有效、可靠的。 |
| 英文摘要: |
| In this paper, a concept of piecing wave front method is developed to solve large nonsymmetric FEM matrix. The developed method has advantages of both piecing method and wave front method which can optimize computational procedure and maintain equilibrium between economic efficiency and storage efficiency. As a numerical example, a FEM matrix of steadily rolling tire analysis is solved by the developed method, which demonstrate the method is effective and reliable. |
