中文摘要:
      拼焊板构件因容易实现轻量化、低成本、短周期成形制造而被广泛应用于飞机、汽车工业中,但在这类构件的塑性成形中,焊缝引入的材料、几何、边界条件非线性显著增加了成形复杂性,导致成形质量及成形极限下降,尤其是在具有强烈不均匀变形特征的弯曲、旋压等局部加载塑性成形中表现得更加明显,极大制约了轻量化拼焊板构件的精确塑性成形。为此,国内外学者在拼焊板构件弯曲及旋压变形机理与成形规律方面开展了大量研究。从焊接材料不均匀力学行为表征、拼焊板构件弯曲及旋压成形有限元建模、焊缝特征对变形行为影响及工艺设计等方面综述了相关研究进展,最后提出了拼焊板构件塑性成形仍面临的关键难题与挑战,对认识和发展轻量化拼焊板构件塑性成形具有重要指导意义和参考价值。
英文摘要:
      Compents with tailor welded plate have gained increasing application in the aircraft and automotive industries because of their advantages: easily achieving forming at light-weight, low cost and short cycle of forming and manufacturing. However, non-linearities of the material, geometry, boundary conditions introduced by the weld increase the forming complexity and deformation unevenness, resulting in a decrease in the forming quality and limit. Especially in the local loading plastic forming with strong uneven deformation characteristics such as bending and spinning, the influences are more obvious. Huge efforts have been made by schoolers at home and abroad to investigate the deformation mechanism and forming law of compents with tailor welded plate in the bending and spinning. This paper reviewed the research progress in the characterization of non-uniform mechanical behavior of welded materials, the finite element modeling, the inflence of the weld characteristics on the deformation behavior and the process design in the bending and spinning of the tailor welded plate. Finally, the key problems and challenges in the current plastic forming of tailor welded platewere proposed. It provides a fundamental guidence for plastic forming of light-weight components with tailor welded plate.
