Mathematical modeling of composite shell assembly

Abstract
Assembly is the final stage of manufacturing machines, accumulating imperfections of the previous stages. For the composite shell of multistage container-based missiles, the existing level of deviation of the compartments often results in the culling of the product due to exceeding the overall dimensions and the limiting values of the assembly efforts. The alignment of the structure on linear bases in the production is fine-tuned, but on the angular bases causes difficulties and requires additional costs. The purpose of this study is to create a mathematical model for assembling a composite shell that takes into account the initial deviations of the compartments. The task of the study is to develop a methodology for simulation and identification of parameters of a mathematical model for the dependence of the overall dimensions and the turn of the product on the parameters of the initial deviation of the compartments. Based on the analysis of the design using analytical geometry and regression analysis, a new method for computer simulation of composite shells with deviations was created. For a set of imperfections, revealed by the results of the real technological process, an imitation experiment was carried out. A random experiment matrix was drawn during the normal distribution of parameters in real ranges of their variation. The result of the study is the technique of the simulation experiment, as well as the regression model of the assembly obtained according to it, which is based on 8 factors. The model is in good agreement with the physical concepts of the technological process and allows optimizing the technological process. It was used in an automated control system for the technological process of building containerbased missiles.
