| 摘 要： | 采用影响面的方法，运用matlab数值分析软件对移动荷载下板的弯矩变化进行了模拟分析。通过控制板的长短边比例，得出不同工况下移动荷载的最不利位置，同时对影响最不利位置的因素进行了相关的模拟研究，得出了长宽比越大的板，其受移动荷载的影响越小的结论。对今后具体的工程计算具有一定的参考意义。

| Abstract: | Influence surface method was introduced in this paper to analyze the changes of bending mo -ment of plate under moving load using the matlab numerical analysis software .Through controlling the length -width ratio of the plate , the most unfavorable position of moving load was concluded under different working con -ditions.At the same time, the simulation research of effect factors of the most unfavorable position was conduc-ted , and a conclusion that the bigger of the length -width ratio , the smaller effect by the moving load was made . It has a certain reference on the calculation of specific projects . |
