Simulation of welding process of side wall of a grain car in SolidWorks Simulation environment

The article is devoted to variance optimization of projecting of technological process of assembling and welding of side wall of a grain car. The process of assembling and welding of the vehicle is subject to significant thermal movement that can affect the performance of the technical requirements for the form and arrangement of surfaces of welded elements. In this regard, it is a pressing task to optimize the design of the solution (in terms of technology) based on a preliminary analysis of the stress-strain state of the structure. In this paper the authors consider the problem of variant design optimization process of welding-assembly sidewall grain carriers. The problem is solved as a time-dependent, unrelated problem of thermoelasticity in the linear formulation using CAD / CAE system SolidWorks (SolidWorks Simulation). The authors have conducted a comparison of the results of the stress-strain state of the model with the deformations obtained on "Ruzkhim-mash" in the experimental production of the side wall.
