摘　　要：从高速转向架的设计原则出发，论述了轻型构架的设计思想，分析了在这种思想指导下结构设计的特点及其应注意的一些问题。采用有限元法对构架强度进行了计算分析，在对轻型构架的强度和力学特性有一定认识的同时，验证了结构设计的合理性。最后，分析了构架静强度试验和疲劳强度试验结果，证明构架达到了工程设计要求。According to the design principle of high speed bogie,in this paper, the design idea of light frame has been demonstrated, and at the same time,the characteristic of structure design and some problems have been analysed as well.By means of finite element method, the strength analysis of light frame has been executed,and the result verifies the rationality of structure design. In addition, by the result of the static and fatigue test for light frame, the good property of light frame has been proved.
