Abstract: In response to the potential deformation issues caused by dynamic vehicle impact during the testing process of the designed and developed automotive spiral rollover test bench, this paper employs the LS-DYNA finite element simulation method to construct a finite element model of the corkscrew rollover test bench. Through simulation analysis of the automotive corkscrew rollover scenario under extreme conditions, the structural strength and dynamic response characteristics of the test bench are evaluated, and an improved optimization plan is proposed to address its existing shortcomings. The analysis results indicate that the optimized spiral rollover test bench can effectively meet the strength requirements for automotive spiral rollover tests, significantly enhancing the reliability and stability of the test bench during experiments.
