轴力的快速计算法研究

Study of fast computing method of the axle

给出了一种根据外力的大小和方向快速绘制构件的轴力图,进而依据轴力图计算轴力、确定危险断面的方法。避免了用传统的“截面法”计算轴力时多次重复画受力图和列解平衡方程式的麻烦。通过算例说明该方法作图简单,结果准确,实用性强。

This paper provides one drawing according to the size and direction of the external force axle of component, and then calculates the strength of the axle, and gives methods to confirm dangerous section according to the axle . It calculates with traditional “sectional law” axle numerous repeated pictures are tested and the preblem is solved. The example of proving this method is given in a simple way. The result is accurate and the practicability is strong.
