Abstract
Increasing the ballistic resistance of the steel railcar tank for carrying toxic liquids is of great significance in terms of preventing liquid leakage. In this paper, three-dimensional numerical simulations have been conducted to study the ballistic performance of railcar tank steel (TC-128) plate under normal and oblique impact. The finite element analysis results in terms of the ballistic limit of TC-128 steel plate are consistent with ballistic limit test results with average error of 8%. Both experimental and numerical simulation results show that the ballistic limit of TC-128 steel plate increased with increasing impact obliquity. A vane structure was proposed to deflect the projectile. As a result, the enhanced impact obliquity increased the ballistic limit of TC-128 steel plate. Two materials, steel 1006 and aluminum were used for the vane structure, respectively. The ballistic limit of the vane-target structure was improved with vane structure obliquity and thickness. At the same vane structure obliquity and thickness, the steel 1006 vane structure is more effective in protecting the TC-128 steel plate than the aluminum vane structure due to higher strength. However, with the same thickness, the “Vane Isolated Performance” (VIP) of the aluminum vane structure is higher than the steel 1006 vane structure because of the lower areal density of aluminum. The analysis was also extended to a double layer aluminum vane structure. The double layer aluminum vane structure could provide better ballistic performance than the single layer aluminum vane structure with the same areal density. Therefore, vane structure obliquity, strength, areal density and distribution density are four most import parameters for vane structure to improve the ballistic limit of TC-128 steel plate. All the simulations were performed in ANSYS AUTODYN finite element code.
