Abstract:The objective of this research project was to develop and analyze a new, cost-effective, MASH TL-6 barrier which would contain a tractor-tank trailer vehicle. To evaluate barrier designs, it was first necessary to develop a validated tank-trailer model which could be towed by a tractor vehicle. This research report describes the development of the tank trailer. A literature review was conducted which evaluated different computational methods to simulate fluid inside a tank. Using geometry of the BKZ 5949 gasoline/oil/fuel tank provided by the LBT Inc., located in Omaha, Nebraska, MwRSF researchers generated a tank, suspension, and fluid model. The model was simulated in static and dynamic configurations and was attached to a pre-existing model of a tractor. Four viable fluid modeling techniques were considered and models of each fluid were implemented into the tank model. The weights of the fluids were calculated based on the empty static weights of the tractor and trailer.
