Abstract
The article discusses the problems of deformation of the roof of passenger car bodies from the effects of excessive solar radiation and the influence of external factors on the strength and stability of the metal structure of the car body. The results of full-scale modeling of the temperature effect on the roof of the wagon body of model 61-4514 with the application of repair loads are presented in the research paper, as well as the dependence of the change in microdeformations (stresses) of the car roof depending on the values of the temperature effect and the combination of test repair loads. The calculation of critical stresses for different cross sections of the corrugations is carried out. Five different variants of cross-sections are studied, and the most favorable variant in terms of stability is selected. Measures to ensure the stability of car body sheathing are given.
