摘　　要：新型3轴转向架用于200km/h速度级电力机车。文章详细介绍该转向架构架的结构特点,并根据ANSYS有限元分析计算结果对该构架进行结构优化设计,确定构架主体合理的截面形状,使其达到强度要求和轻量化目标。New type 3-axle bogie is designed for the electric locomotive at 200 km/h. This article presents this bogie frame＇s structure characteristics and results of its stress calculation by ANSYS software. The structure design is optimized and appropriate sections of the bogie frame＇s main body are decided. The bogie frame satisfies the strengthen requirement, and the lightweight goal are achieved.
