| 摘 要： | 目前角钢和型钢压弯、压凹时的变形力多根据经验确定,笔者由功的平衡原理出发,考虑其变形时的应力状态,得出型材在压弯成形时的精确变形,并对所得数学式进行试验验证,二者结果十分接近,该式有很好的推广应用价值。

| Abstract: | At present, experience plays a main part in determining the distorting and deforming strength of angle section and section steel because of the neglect of the consideration of the stress of the material in deforming. Therefore, the quality of finished products is difficult to control. Based on the balance theory of work and the consideration of the stress condition in the course of changing, the author gets the accurate stress in deforming and verifies by experiment which proves to be very close. |
