摘要
本文通过对平车承载的受力分析和对平车几种典型中梁结构的强度试验应力分析,探讨了不同载荷工况对平车结构强度的影响及结构对应力的影响,并提出纵向作用的载荷在底架各纵向梁中的分配与结构的关系。
In this paper, by the analysis for load bearingforce and for stress (acquired in strength tests) ofseveral typical structured center sills on the flat cars,discussed are the influence of different loading cond-itions on car structure strength and the influence ofstructure on stress. Then the relations between thestructure and the longitudinal effected load distributionon all longitudinal sills of underframe are put for-ward.
