Lightweight structure is an important method to increase vehicle fuel efficiency. High strength steel is applied for replacing mild steel in automotive structures to decrease thickness of parts for lightweight. Howeve...
为了展平成形后的工件或修正初始毛坯构形,提出了一种基于一步逆成形有限元法的约束展平算法[Constrained Unfolding Algorithm based on one-step inverse FEM(Finite Element Method),简称CUA]。CUA将展平或修正过程考虑为一个约束优...
