| 摘 要： | 通过建立完整的汽车-三波护栏-乘员-座椅-安全带系统模型,应用LS-D Y N A研究了三波护栏在强力撞击下的耐撞性与吸能特性,得出了梁板是吸能主体、三波护栏对失控车辆具有很强的引导能力、室内乘员的安全性能够满足要求等结论,指出了三波护栏在抵御强力撞击方面的主要问题是护拦的完整性不足,为三波护栏耐撞性能的提高指明了方向。

| Abstract: | The crashworthiness and the energy-absorbing characteristic of the three-beam guardrail structure under mighty impact are studied using the LS-DYNA the integrated model of "automobile-three-beam guardrail structure-passenger-passenger seat-safety belt" is created.The results indicate that the beam is the main body for energy absorbing,the three-beam guardrail structure is better in guiding the automobile out of control for the safety of the passenger,and so on.The primary problem is the lack of the integrality of the three-beam guardrail structure to resist mighty impact,and the direction to improve the crashworthiness of the three-beam guardrail structure is shown. |
