摘　　要：柔性构架式转向架能够同时弥补三大件式转向架抗菱形变形能力弱以及整体构架式转向架适应线路不平顺能力差的缺点。提出了一种铰接式柔性构架式转向架方案,对转向架构架的扭曲刚度和抗菱刚度进行了理论推导,并通过有限元软件对公式进行了仿真验证。The flexible frame bogie can simultaneously make up for the shortcomings of the weak anti-diamond deformation ability of the three-piece bogie and the poor ability of the overall frame bogie to adapt to the line irregularity.In this paper,an articulated flexible frame bogie is proposed.In addition,the torsional stiffness and anti-diamond stiffness of the bogie frame are theoretically deduced and the formulas are simulated and verified by finite element software.
