摘要
采用CAE仿真软件,研究碳纤维复合材料转向架的工程应用。仿真条件下比较碳纤维复合材料转向架、钢制转向架、铝合金转向架的材料力学、结构力学、工程力学特性,发现前者均有显著优势,进一步分析中发现碳纤维复合材料转向架的运行结构温度高于传统转向架,且其材料本身对高温耐受性较低,且碳纤维复合材料转向架的理论安全运行距离显著短于传统转向架。最终认为后续应在碳纤维复合材料转向架的运行温度控制方面进行重点研究。
The engineering application of CFRP bogie is studied by using CAE simulation software.Comparing the material mechanics,structural mechanics and engineering mechanics characteristics of CFRP bogies,steel bogies and aluminum alloy bogies under the simulation conditions,it is found that the former has significant advantages.Further analysis shows that the operating structure temperature of carbon fiber composite bogies is higher than that of traditional bogies,and the material itself has low high temperature resistance.The theoretical safe running distance of CFRP bogie is significantly shorter than that of traditional bogie.It is concluded that the following research should focus on the operation temperature control of CFRP bogies.
