摘　　要：与传统的轧制板材相比,采用高压板料成形工艺加工的柔性辊压板坯可以实现工件的优化生产,使其应用于各种特殊场合。本文通过有限元法实现了对柔性辊压板坯加工过程中两个主要阶段(柔性轧制和高压板料成形)的数值模拟与优化。优化过程包括对板料加工链和载荷条件下工件性能两方面的优化。数值模拟与试验结果的对比表明,有限元方法与优化工具的组合成功实现了整个加工链和工件性能的数值模拟与优化。The high-pressure sheet metal forming of tailor rolled blanks allow the production of optimized components specially developed for their future function,which can not be made from conventionally rolled sheet metal.This research aims at showing that the two main processes,i.e.,flexible rolling and high-pressure sheet metal forming,can be well represented in finite element simulations.The optimization process includes the optimizing of blanks process chain and the tool performance under a predefined load.The result shows that it is possible to simulate and optimize entire process chains and the product properties by linking the finite element models with a combinatory optimization tool.
