Application of Computer Simulation to Ensure Compliance of Vehicle Underrun Protective Device with the Requirements of UN Regulation No. 58

Abstract

The methodological recommendations of the process of improving the design of the rear underrun protective device (RUPD) are considered and described based on the results of computer simulation of tests (virtual tests) to ensure compliance with the requirements of UN Regulation No. 58 Revision 3 (hereinafter the Regulation). An example of creating a computer model, carrying out virtual tests with subsequent refinement of the design of the RUPD is given to ensure compliance with the technical requirements of the Regulation. The calculation model is developed using the ANSYS Workbench and LS-PrePost software packages. The calculation is performed in LS-DYNA program. Processing and analysis of computer simulation results are performed in the LS-PrePost program.
