具有承载车体的内燃机车在铁路运输中日益得到推广。在这种结构中加强壁板不仅作为防护用,而且也作为一种主要的承载构件用。因此,在车体具有最小的重量情况下,就可以保证车体具有必需的强度和刚度。内燃机车车体与车辆车体、船体以至在某种程度上与飞机机身有一定的相似之处,同时又具有一系列独有的特性。尤其是,大量的切口、切口的分布及大小横断面的轮廓形状、加强壁板的特性以及受力情况等等均有独特之处。因此对车体要求进行专门的研究。随着这种结构的改进与发展,就提出了发展其计算理论的迫切任务。车辆的计算方法在封闭壳体型的车辆车体的现代实际计算方法中,考虑到窗、门切口
Diesel locomotives with load-bearing bodies are increasingly being promoted in railway transportation. Reinforced siding in this construction is used not only as a protective but also as a primary bearing member. Therefore, with the minimum weight of the body, it is possible to ensure that the body has the necessary strength and rigidity. The diesel locomotive body, the vehicle body and the hull have a certain degree of similarity with the aircraft fuselage, but also have a series of unique features. In particular, a large number of incisions, incisions and the distribution of size and size of the cross-sectional shape and shape, to strengthen the characteristics of the siding as well as the force situation and so on are unique. Therefore, the body requires specialized research. With the improvement and development of this structure, an urgent task of developing its computational theory has been put forward. Calculation method of vehicle In a modern practical calculation method of closing a vehicle body of a shell-type vehicle body, taking into account a window, a door cut
