In modern day industry, an emphasis of lean engineering has taken place in order to save time and resources while delivering better products than competitors. Furthermore, great strides in production and manufacturing have raised efficiency and saved companies time and money. However, testing and certification, although essential, can be a costly procedure in between the stages of design and production. In an effort to enhance and supplement the structural testing methods, specifically crash analysis, a simplified yet accurate FEA modeling method is developed to better understand a design performance during physical testing. However, the methodology will not be a substitute for real world certification testing, but rather a means to save time and money so as to offer performance and design insight. A critical area of performance is crash test analysis. The modeling method in this presentation was based upon crash conditions referenced from FAR 25.562 as well as physical test methods for crash analysis. Furthermore, this modeling method was directly compared to real world test data. The crash modeling utilizes HyperMesh, HyperCrash, and LS-DYNA so as to offer insight into structural performance.
