| 中文摘要: |
| 按组成材料和横截面大小的不同,把复合棒分成若干单元,每单元两端的位移、截面转角、弯矩以及剪力间的关系用矩阵表示,各单元矩阵相乘即得到复合棒总的矩阵,最后由此求解复合棒的共振条件,以及两端振速比,还给出了应用例。 |
| 英文摘要: |
| A composite bar is divided into several elements in terms of their materials or cross-section areas. The relation between displacement、flexural angle、moment and shear stress of the two end surfaces of each element is expressed by using a matrix. For a composite bar, the relation ship can be expressed by a general matrix, which is the multiplication of matrixes of elements. From the general matrix, the resonant frequency and velocity gain can be calculated. The application of this method is also illustrated in this paper. |
