摘　　要：分析肋骨弯曲加工中产生长度伸缩变形对成形过程及结果的不利影响,提出以型材中性轴曲线为成形依据的新控制原理及测量方法,以实现完全避开伸缩变形影响的高精度弯曲成形。The bad influence of the tensile and compressive deformation upon the shape forming process and results in frame bending is analyzed. The new controlling principle and measuring method based on the neutral axis line of beam for shape forming are put forward in order to get high accuracy by avoiding the effect of tensile and compressive deformation.
