Abstract:Transportation Technology Center, Inc. (TTCI) performed a dynamic impact test of a diesel multiple unit (DMU) fuel tank at the Transportation Technology Center (TTC) in Pueblo, CO, where an impact vehicle weighing approximately 14,000 pounds equipped with a rigid 12-inch by 12-inch impactor head struck the bottom surface of a DMU fuel tank. At 11.2 mph, the impactor struck the target area, centered over two internal baffles. The test resulted in a maximum indentation of approximately 8 inches. Following the test, TTC cut the fuel tank open to inspect the damage to the tank’s internal structure. This revealed that several internal baffles in the surrounding area of the impact location buckled. The John A. Volpe National Transportation Systems Center developed the pre-test finite element (FE) model of the DMU fuel tank and impactor. Prior to the test, engineering drawings and computer-aided design (CAD) geometry were used to generate a detailed FE mesh of the fuel tank. The pre-test FE model was used to plan for instrumentation range and placement, as well as to estimate the desired test speed. The FE models of the fuel tank and the actual test results were in agreement. FRA can now use the validated FE model to simulate other impact scenarios of this fuel tank.
