| 摘 要： | 本文介绍的是利用有限差分法求解箱形结构的挠度。箱形结构是梁与板的组合结构,工程上经常遇到。首先,我们分别建立板与梁的差分方程,再根据梁的挠度与板的挠度一致,写出箱体的系数矩阵,编程计算求出相应点的挠度。

| Abstract: | In this paper,it is introduced that the deflections of box-like structure are calculated by finite differential methods. A box-like structure is a combination structure of plates and beams,which is not unusual in engineering. The differential equations of plates and beams are established first. Then according to the same deflection of plate and beam,the matrix of coefficient can be written and their deflections can be calculated by a computer program. |
