| 摘要： | The report summarizes the research efforts of using finite element modeling and simulations to evaluate the performance of double-faced W-beam and Thrie-beam guardrails at different installation heights and under Manual for Assessing Safety Hardware (MASH) Test Level 4 (TL-4) and Test Level 5 (TL-5) impact conditions. The simulation results demonstrated the effectiveness of the double-faced 29- and 31-inch W-beam guardrails and Thrie-beam guardrails, with wood- and steel-blockouts, placed on a flat median under MASH TL-4 and TL-5 impact conditions. |
