新型高速公路中央分隔带护栏的设计与研究

Design and Research for a New Highway Median Guardrail

简要回顾高速公路护栏的发展现状,结合中央分隔带护栏的设计原则和要求,致力于提高护栏的整体性能,设计出一种新型中央分隔带护栏。采用大型有限元软件ANSYS,通过对新型护栏施加相当于汽车碰撞时产生的冲击力大小的载荷,观察求解结果,分析检验护栏的强度。最后展望未来研究方向。

Brief review of the development of highway guardrail status quo,with the median guarkrail design principles and requirements,a new median guardrail is committed to improving the overall performance.Using finite element software ANSYS,the new guardrail imposed by the equivalent of auto collision impact force when the size of the load,the results observed solving to test the strength of guardrail.in the end,there will be a prospects for future research.
