| 中文摘要: |
| 本文从非线性弹性理论出发,采用泛函内积形式,建立了悬索非线性计算模式。提出了变原长迭代计算的基本思想,就一端固定、另一端张力已知的悬索模型,从Reissner变分理论出发,导出了该模式的非线性有限元的基本方程,使计算量大大减少。 |
| 英文摘要: |
| This paper applied nonlinear elastic theory to cable structure, by means of variational and inner product, established nonlinear computation model of cable. Author proposed new ideal for cable's initial length to change during iteration. For cable, which is fixed at one end and whose tensile force is known at other end, by means of Reissner principle, author established elementary equations of nonlinear finite element. This model comparing with that of reference[2], computation time is reduced greatly. |
