Prediction of product assembly errors using real part models

Abstract

A method has been developed for calculating the parameters for assembling parts based on the creation of real models of their surfaces. For the construction of actual models, a special method for analyzing the measured surfaces and a software application were developed. Measurement analysis includes smoothing outliers, ordering the grid of points on the surfaces, and additional mathematical referencing. The assembly process is modeled in the ANSYS. The results of calculations for the assembly of two parts joined at their flat surfaces by means of a bolted joint are given. The analysis of the obtained results was carried out. It showed the possibility of using the developed methodology for predicting the parameters of gas turbine engine assembly units. The line of further research related to the study of the relationship between assembly parameters and influencing factors has been determined.
