| 中文摘要: |
| 介绍了冲压领域常用板材成形性能试验方法，包括国标收录的拉深、凸耳、杯突、扩孔、弯曲、锥杯、FLC试验，以及国标没有收录的抗凹性、摩擦、拉弯回弹、方板对角拉伸、波纹度试验等试验方法，对各种试验方法从试验目的、试样制备以及试验仪器选用等环节作了详细介绍。然后，针对目前成形性能试验应用中存在的一些问题进行了分析，并给出了建议。最后，对板材成形性研究领域最新的试验技术以及发展前景作了阐述。 |
| 英文摘要: |
| This paper introduces the test methods of sheet metal formability commonly used in stamping field, including deep drawing test, earing test, Erichsen cupping test, hole expansion test, bending test, conical cup test, FLC test as stipulated in the national standards, as well as sinking-resistance test, drawing-friction test, springback evaluation in stretch bending test, Yoshida buckling test etc. which were not included in the standards. Test methods are introduced in detail from the aspects of test purpose, sample preparation and selection of test instruments. Then, some problems existing in the current test application are analyzed and some suggestions are given. Finally, the latest experimental technology and development prospects in the field of sheet metal formability research are described. |
