承载式车体在机车制造中已用得越来越多。这种车体可以降低机车重量,增强结构刚度,提高运行安全性,减少维修费用。选择车体型式是很重要的。早在二十年代末期,在飞机制造师面前提出了同样的问题。[10] 与其他学者的理论研究和中央空气流体动力学研究院的试验证明:采用无斜拉杆的薄壁系统是合理的。按 The load-bearing body has been used more and more in locomotive manufacturing. This body can reduce locomotive weight, enhance structural rigidity, improve operational safety and reduce maintenance costs. It is important to choose the body type. As early as the late 1920s, the same question was raised before the aircraft manufacturer. [10] Theoretical studies with other scholars and experiments conducted by the Institute of Central Air Hydrodynamics prove that it is reasonable to adopt thin-walled systems without inclined rods. press
