This paper presents improvement of the crashworthiness of DH4-1 Iran Pardis train set using thin walled tubes in the nose structure. The impact of train set with other moving rolling stocks is simulates using LS-DYNA software. The model is verified as per ECE R 66 standard. The absorbed energy ratios and hourglass energy are calculated and reported. It is demonstrated that by using thin walled tubes, it is possible to delay the shock and considerably reduce the amount of shock load to the vehicle structure.

Abstract


This paper presents improvement of the crashworthiness of DH4-1 Iran Pardis train set using thin walled tubes in the nose structure. The impact of train set with other moving rolling stocks is simulates using LS-DYNA software. The model is verified as per ECE R 66 standard. The absorbed energy ratios and hourglass energy are calculated and reported. It is demonstrated that by using thin walled tubes, it is possible to delay the shock and considerably reduce the amount of shock load to the vehicle structure.
