摘要: 阐明了柔性轧制方法成形三维曲面的基本原理和两种典型曲面成形的控制方法,分析了板料变形区的应力、应变状态和3个主方向的变形及其相互关系。通过有限元方法模拟了两种曲面的成形过程,结果表明:成形鞍曲面和凸曲面时分别出现正、负宽展;无论是成形凸曲面还是鞍曲面,纵向纤维的相对伸长量越大,纵向变形越大。进行了成形试验,测量和分析结果表明:成形件与目标值相比,最大成形误差不超过3.2 mm,成形曲面质量好,回弹小。

Abstract: The forming principle of three-dimensional surface by flexible rolling and the control methods of two kind of typical surface forming are illustrated. The stress and strain states of the deformation zone are analyzed. The deformations and their relationship in the three principle directions are also analyzed. The forming process of two typical surfaces are simulated using finite element method. Simulation results show that the positive and negative spreads appear respectively when saddle and convex surfaces are formed. No matter of convex surface or saddle surface, the larger the relative elongation of longitudinal fibers is, and larger longitudinal deformation is. The flexible rolling forming experiments are conducted. The measurement and analysis results show that, compared with the target value, the maximum forming error is no more than 3.2 mm. Therefore, the quality of the forming surface is good and the springback is small.

Key words: material synthesis and processing technology, flexible rolling, three-dimensional surface, deformation analysis, forming simulation
