摘　　要：对单、双腹板侧梁焊接式货车转向架构架的刚度、静强度和疲劳强度进行了对比分析。结果表明,在侧梁抗弯截面模量相同的前提下,单腹板侧梁焊接构架具有较好的柔性,双腹板侧梁焊接构架具有更好的静强度和疲劳强度,应力分布趋于均匀,承受交变载荷的能力更强,更能适应线路条件差、工况恶劣的环境。The comparison analysis is made on the stiffness,static strength and fatigue strength of the side sill welding type freight car bogie frames with single web plates and double web plates.The result shows that,with the same bending modulus of section of side frames,the side sill welding frames with single plates have fairly good flexibility,however,the side sill welding frames with double plates have better static strength and fatigue strength with stress distribution tending to be even,have greater capacity to withstand alternating load,and can better adapt to the environment with bad track conditions and foul working conditions.
