| 摘要： | Phase 2 of this project is a continuation from Phase 1 and investigates the survivability of railroad tank car top fittings in rollover scenarios using Failure Element Analysis techniques. It also explores additional protective concepts intended to survive more severe impacts than those of the Phase 1 study. Three new protective concepts, a rollbar assembly using an elliptical shape to allow the car to roll with little resistance, a fabricated deflective skid, and recessed fittings, are developed and analyzed in Scenario 1 (severe rollover as in the Phase 1 study). A third scenario is simulated for the new concepts, which includes longitudinal car velocity and impact into a concrete barrier. |
