文章通过大量的计算,从受力的角度对两种机车车体结构型式做了比较,指出在通常的设计和制造工艺条件下,桁架式车体要优于框架式,文章提出,在车体设计的不同阶段应采用不同的计算模型,并对车体结构模型化的一些具体问题进行了研究,文章提出了对车体进行强度计算时应考虑的工况。 The article through a large number of calculations, from the perspective of the force of the two types of locomotive car body structure are compared and pointed out that in the general design and manufacturing process conditions, the truss body is better than the frame type, the article proposed that in the body Different calculation models should be used at different stages of the design, and some specific problems of the car body structure modelling should be studied. The article puts forward the conditions that should be taken into account when calculating the strength of the car body.
