ABSTRACT
The objective of this research project was to develop a new, cost-effective, MASH TL-6 barrier. A literature review on prior Test Level 5 and Test Level 6 barriers was conducted, and the cost of current TL-5 and TL-6 barriers was established. Existing and modified design procedures for roadside barrier were reviewed as well as current TL-6 design forces. A preliminary TL-6 truck model was developed in LS-DYNA. The minimum barrier height to contain a tractor-tank vehicle was determined to be 62 in. for a rigid, vertical-faced barrier through LS-DYNA computer simulation. Recommendations for how to improve the tank-trailer model were presented.
This is the End of Year 1 project report. The End of Year 2, 3, and 4 reports can be found under the following report numbers:
TRP-03-430-20 - End of Year 2
TRP-03-457-21 - End of Year 3
TRP-03-463-23 - End of Year 4 - contains full-scale crash test no. MTL6-1
