摘　　要：阐述了随着列车运行速度的提高，降低机车自重的重要意义。通过对ＳＳ８型客运电力机车车体钢结构减重的研究，提出了对于车顶盖不能与车体固结在一起共同承载的机车车体结构，采用按整体承载思路，沿车体纵、横向组成一定数量的封闭框架，并协调有关构件的刚度，尽可能发挥各构件的承载作用的车体结构设计方案，并通过动态分析，验证了这一方案的可靠性。This paper presents the significance of the decreasing in tare weight of the locomotive with the speed increases of the train.By the studiea of the lightening of the car-body steel structure ofSS8 type passenger electric locomotive,this paper gives the design of the car-body structure which theroof don't be fixed to the body-according to the light of the integral load-bearing structure,forming a number of confining frame on the body's vertical/horizontal sides,and harmonizing thestiffness of related components,thus to make full use of those load-bearing functions. The reliabilityof the design of car-body structure has been proved by the dynamic analysis.
