摘要
首先给出计算弹性矩形截面直杆扭转问题的一种新方法,笔者采用矩形膜振动位移函数做为求解该问题的应力函数.该方法简单易行、精度高.然后采用了特殊坐标变换式解决了求解任意多边形截面的等直杆扭转问题.
This paper offers a new method to calculating torsion problem of a straight bar with rectangular cross section. A stress function is the displacement function of rectangular film in transverse vibration, which is an simple engineering calculating. And it also puts forward a new way of changing coordinate to deal with the torsion problem of a straight bar with many sides cross section.
