摘要/Abstract

摘要： 针对复杂车身梁类制件在多步冲压加工中应用广泛但技术实施难度大的特点，文章以典型复杂车身结构件为研究对象，系统剖析了制件多步冲压成形的基本工序，明确了成形过程中的关键难点与技术要点。在此基础上，创新性设计了制件的 12 工序排样图，并围绕该排样图开展了全面的工艺分析。通过构建全工序有限元模型，深入阐述了增量加载有限元法的仿真数学模型，经精确计算，最终获得了满足工程要求的全工序有限元仿真分析结果；通过实际冲压试验与产品质量检测，对 CAD/CAE 仿真方案的有效性和合理性进行了全面验证。该研究为车身结构件的级进模开发过程提供了一套可行的排样工艺设计与全工序有限元仿真分析方法，不仅深化了制件成形性的研究维度，更从理论与实践层面为汽车复杂梁类制件的制造工艺优化及质量控制提供了重要指导。

Abstract: Aiming at the characteristics of complex body beam components widely used in multi-step stamping processing but with high technical implementation difficulty, this paper takes typical complex body structural components as the research object, systematically analyzes the basic processes of multi-step stamping forming of the components, and clarifies the key difficulties and technical points in the forming process. On this basis, an innovative 12-process nesting diagram for the components is designed, and comprehensive process analysis is carried out around this nesting diagram. By constructing a full-process finite element model, the simulation mathema-tical model of the incremental loading finite element method is deeply expounded. Through precise calculation, the full-process finite element simulation analysis results meeting engineering requirements are finally obtained. The effectiveness and rationality of the CAD/CAE simulation scheme are comprehensively verified through actual stamping tests and product quality inspections. This study provides a set of feasible nesting process design and full-process finite element simulation analysis methods for the progressive die development process of body structural components. It not only deepens the research dimension of component formability but also provides important theoretical and practical guidance for the manufacturing process optimization and quality control of complex automotive beam components.
