摘要
研究了整体结构件校正需要满足的基本曲率关系 ,进而分析了曲率与弯矩的关系。建立了校正整体结构件弯曲变形的弯矩方程和校正曲率方程。为了便于生产操作 ,给出了校正工件的加工变形所需压下位移量的计算公式。
The relationship of several kinds of curvatures with that a large integrated part must be satisfied during its straightening process is studied. The correlation of the workpiece bending curvature and its bend moment is further analyzed. A bend moment equation, as well as a straightening curvature equation, which are applied to describe the state of straightening bend distortion, are established. For operating convenience, a formula that is used to calculate the stroke of pressing down for straightening manufacturing distortion is given. Finally, the straightening parameter limit is studied to ensure the workpiece safety.
