为设计出一种适用于道路抗撞结构(即护栏)立柱动态冲击试验的新型台车,文中以《National Cooperative Highway Research Program Report 350》和《公路护栏安全性能评价标准》(JTG B05-01—2013)为新型台车设计参考依据,并基于有限元数值分析法将《德国2020高技术战略》中私人订制设计理念融入新型台车设计,即参考汽车理论和汽车设计,在新型台车质心前后对称地设计配重盒并通过添加配重块的方式实现了台车的私人订制,使其质量可在1.1~1.8 t范围内变化。分别建立了新型台车-立柱和传统台车-立柱有限元动态冲击模型进行对比分析及新型台车极限工况分析,得出:传统台车质量固定,不能很好地完成抗撞结...

In this article,in order to design a new bogie which is applicable for the dynamic impact test of the post with the road anti-collision structure (that is guardrail),the regulations including NCHRP 350 and JTG B05-01—2013 serve as the reference; based on the finite-element numerical analysis,the design concept of private customization in German 2020 is incorporated. With the aid of the automobile theory and the automobile design,the counterweight boxes are developed symmetrically in front of and after the centroid of the new bogie,and the weig...
