Vibration frequency of modified wave beam guardrail based on collision simulation and vibration acceleration analysis

Design of the new W-beam guardrail terminals structure and simulation in full collision

“…The most important traffic safety facility on highways is guardrails, which can prevent vehicles from rushing out of the road and reduce the serious consequences of accidents [1,2] . However, there are still some traffic accidents related to the unreasonable setting of roadside guardrails, such as insufficient anti-collision level of guardrails in key areas, lack of safety treatment at guardrail ends, and lack of transition between rigid guardrails [3] . The most prominent and serious cause of accidents is the lack of safety treatment at guardrail ends.…”
