Influence of Symmetry of Tightened Parts on the Force in a Bolted Joint

This article discusses the issue of force behavior in a pre-tensioned bolt that is part symmetrical flange connection, loaded with an operating load parallel to axis. The first describes being dealt detail. next offers brief description generally known theoretical approach solution, and also outlines limitations this approach. followed by analysis working analyzed device, using Finite Element Method (FEM). In article, comparison several different approaches solution can be found, experiment preparation its results. obtained values serve as subject for reverse iterative carried out ANSYS software. aim find proper modification symmetric calculation model would consistent results measurements from technical practice. All achieved are described final article.
