| 摘要： | Researchers at the Texas A&M Transportation Institute (TTI) designed and tested a Manual forAssessing Safety Hardware (MASH) Test Level 4 (TL-4) compliant metal guardrail system. The researchersfirst developed several preliminary design concepts of the guardrail system, one of which was selected by theTexas Department of Transportation (TxDOT) for further development through simulation and crash testing.The researchers then developed a full-scale finite element model of the selected system and performedimpact simulations under MASH TL-4 impact conditions. Using the results of these impact simulations, theresearchers made further improvements to the guardrail design and developed the final system design detailsfor crash testing. TTI then constructed the guardrail installation and performed MASH Test 4-12 with a singleunit truck, MASH Test 4-11 with a pickup truck, and MASH Test 4-10 with a small car to meet MASH TL-4compliance criteria for longitudinal barriers. |
