Abstract

Abstract

In order to reduce the serious accidents caused by impacting W-beam guardrail terminal, the properties of traffic flow were analyzed, the impact test methods and acceptance criteria for the terminal were brought out based on referring to correlative domestic and overseas standards, a new type of W-beam guardrail terminal was developed by using finite element analysis and full-scale impact tests, which meets acceptance criteria. It is pointed that passengers can be protected for that the acceleration of vehicle gravity center is less than 20 g by rolling W-beam to absorb accident car's kinetic energy, which keeps W-beam from piercing into car or accident car from turning over, and the containment level of standard section for barrier is guaranteed by enough restraining force at the guardrail terminal. The result indicates that the performances of the terminal meet acceptance criteria and can protect accident vehicles.
