Car body part pre-install deformation finite element virtual assessment analysis

在车身工艺同步工程阶段,通过有限元仿真方法对车身制造过程中预装零件的不同产品设计方案进行虚拟评估分析,根据分析结果指导零件设计优化。该仿真方法在生产实物阶段得到验证,可提前识别制造过程质量风险。与传统的通过经验评估判断零件预装变形的方法相比,在工艺同步工程中应用有限元仿真技术,为解决车身制造过程中的复杂工况变形问题提供理论分析方法和依据,可靠性高,并达到缩短制造周期、降低制造成本的目的。

Finite element virtual assessment did for car body part pre-install deformation based on different product design proposals during process simultaneous engineering.The method that validated during car body pre-build can instruct product design and identify manufacturing quality risk in advance.Compared with traditional method that identify part preinstall deformation by experience,finite element simulation method can provide theoretical evidence to solve complicated manufacturing deformation issue in body process simultaneous engineering,and the reliability is high.What’s more,it is helpful to shorten manufacturing time and reduce cost.
