A method is proposed to estimate the loading capacity of passenger car bodies with two-layer side wall lining using the finite element method and mathematical modeling of the car movement along real track irregularities. The interaction of the side wall lining sheets connected by spot welding is described. Various types of two-layer lining are considered. The estimation is given to the influence of the method of the two-layer lining on the stress-strain state obtained by finite element calculation according to the dynamic parameters of the car when modeling its movement along real track irregularities. It is found out that when estimating the stress-strain state in the zones of welded joints, it is advisable to use detailed design diagrams with modeling of their geometry. When assessing the strength of the body bearing structure or the stress-strain state of large body components, it is advisable to use design diagrams describing welded joints with special rod finite elements. When assessing the dynamic characteristics of a car moving along the track irregularities using a hybrid dynamic model, design diagrams with the description of a two-layer lining with orthotropic materials are applied. Also, when using appropriate design diagrams in these types of studies, a sufficient degree of results accuracy obtained is ensured.

The lining stability of the side walls and roof of the passenger car body is assessed during repair work related to its asymmetric lifting with a jack at one end of the body. Using mathematical modeling, the lifting height is determined which is necessary to ensure the possibility to dismantle the springs of the spring set of the central suspension. The stability of the reinforced lining of the car body was assessed using the developed problem-oriented elastic-dissipative finite element model of the supporting structure of the passenger car body. The calculations are performed in a static non-linear formulation, taking into account the geometric nonlinearity and non-conservativeness of the operating loads. The stability of the reinforced load-bearing lining of the car was assessed both for the initial structure and for a structure with geometric imperfections such as technological loss. The analysis of the research results allows to conclude that during the technological operation associated with lifting the passenger car body with a jack under one support, it can lead to a loss of stability of the sill belt lining of the side wall and the smooth sheathing of the roof slope. The results obtained agree with the results of the inspection of full-scale cars in operation.
