| 中文摘要: |
| 论文阐述了动力松弛法计算静力问题的原理,分析了Rayleigh阻尼对计算的影响,提出了一种对质量阻尼和刚度阻尼参数取值的新方法。这种取值方法可以避免计算结果的振荡和过塑性的问题,并利用实例计算进行了对比分析,验证了本文中Rayleigh阻尼取值的合理性。 |
| 英文摘要: |
| The principle of calculating static mechanics using dynamic relaxation method is interpreted, and the effect of Rayleigh damp on calculation is analyzed. Then a new method on value adoption of mass damp and rigidity damp is put forward. This method can avoid surging and being over molded of calculation. At last, analysis for comparison is done by an example to prove the rationality of value adoption of Rayleigh damp in this paper. |
