摘要/Abstract

摘要： 通过理论分析对球形件在柔性压辊拉伸成形装置上的成形位移加载方式进行了研究。利用几何解析方法,建立了球形件成形时各子压辊的位移量和板材延伸率的关系。对2024-O板料利用位移加载进行数值模拟,并与力加载的分析结果进行对比,结果表明位移加载的等效应力和等效塑性应变分布比较均匀。实验结果表明这种位移加载方式可行。与力加载相比,本文几何解析法可以快速计算出各个压辊加载所需的位移量,大大节省了调试时间,对蒙皮拉形有一定的指导意义。

Abstract: Through the theoretical analysis, the forming loading displacement method for the spherical part was studied based on the flexible roller stretch forming device. Using geometric analysis method, the relationship between the displacement of each roller and the elongation of the metal sheet was established for spherical part forming. Simulation analysis of the material of 2024-O was performed by loading displacement, the result was compared with the analytical result of the force loading, it was found that the distributions of both the equivalent stress and equivalent plastic strain gained by the loading displacement are relatively uniform. Utilizing the flexible roller stretch forming device to form the spherical part,the test results show that the displacement loading method is feasible. Comparing with the force loading, the geometric annalysis method could quickly calculate the required displacement of each roller for the load, saving enormous debugging time, providing some guidance for the stretch forming of the skin.

Key words: materials systhesis and processing technology, stretching, flexible roller, spherical part, elongation, loading displacement
