Abstract
With the gradual expansion of the market for small-scale, multi-variety, small-volume production electric vehicles, the need arises to develop appropriate crash stability evaluation standards and techniques. This study focuses on utilizing a space frame suitable for small-volume production vehicles for design and manufacturing purposes. The research involves measuring acceleration values and comparing them between computer simulation crash analysis and crash tests conducted on an actual fixed wall frontal crash scenario. The collision analysis and test were performed with a collision speed of 50 km/h, and the measured acceleration values were compared with those obtained from finite element analysis. The results of the crash analysis and crash test indicate that in both cases, the main frame experienced breakage, with the analysis results aligning closely with the actual test outcomes. Although some performance conditions led to differences in acceleration values, overall, the trends exhibited similarities between the crash analysis and crash test. Based on these findings, computer simulation can be employed as a substitute for the crash analysis vehicle certification method when modifying the certification method for low-scale production vehicles. This research contributes to developing crash stability evaluation standards and techniques for small-scale production of electric vehicles. The study demonstrates the feasibility of utilizing computer simulation as an effective tool for crash analysis vehicle certification, providing valuable insights for future certification methods and improving the efficiency of small-volume production vehicle evaluation.
