| 中文摘要: |
| 提出一种分析粘弹性结构自振特性的数值方法,通过弹性等效空间特征值问题及一个代数方程的求解,得出粘弹性结构的频率及振型。此外建立了薄板的粘弹性动力方程并给出相应的求解方法。文中做了数值验证。 |
| 英文摘要: |
| A numerical method for analysing free vibration behavior of viscoelastic structures is presented. By virtue of solving a problem of eigen value in an equivalent elastic space and an algebraic equation, the frequencies and modes of viscoelastic structures could be obtained. Also, the viscoelastic dynamic equation for thin plate is established and corresponding method for solution is given. Numerical verification is exhibited in the paper. |
