| 摘 要： | 提出一种应用于金属热塑性成型数值模拟中的时空耦合算法。将热力交织的非稳定非均质问题在时间和空间上分解开来,变成瞬间的稳定、均质问题和热力承转反馈的递推过程,并且能够进行各种关联成型行为的穿插计算,为成型模拟提供了更大的发展空间。

| Abstract: | A method of space-time coupling calculation applied to numerical simulation of metal hot working process is come up with. The unsteadiness and ununiformity of metal deformation, that there are heat and force to affect together, are simply turned into steadiness, uniformity in split second and deductive process of force-heat delivered and fceded back. Alternate calculation that various forming action is involved in is carried out, and the available capacity is provided for further development of forming simulation too. |
