| 摘 要： | 在不同的模具温度下,对常用的半圆形拉深筋进行了一系列拉深筋阻力(DBRF)试验.试验结果表明,随着模具温度的提高,拉深筋阻力会有很大的变化,这种变化会对DBRF解析计算模型的精度产生不容忽视的影响.考虑到模具温度以及R/t(压筋半径/板料厚度)的影响,提出一个新的DBRF解析计算模型.相较于几种常用的计算模型,新模型计...

| Abstract: | With different die temperatures,a series of drawbead restrain force(DBRF) tests were carried out by applying normally used half-round drawbead.The results show that the DBRF changes greatly with the increase of die temperature,which has unnegligible influence on the accuracy of the mathematical solution model for DBRF.Considering the influence of die temperature and the ratio of R/t(drawbead radius / sheet thickness),a new improved mathematical solution model for DBRF was proposed.Compared with several normally used mathematical solution models,the new model has a maximum error of 7% in calculating DBRF,which has a higher solution precision. |
