Modelling and Simulating the Problem of Bolts Unfastening in Bolt-Jointed Two-Part Autoclave Subjected to Variable Thermal Stresses

Abstract

In this Research we treat the bolts unfastening problem in bolt- jointed two-flange autoclave, by bolts with big diameters. The gasket of Gore-Tex guarantees the sealing-off process. This mechanical system requires a complex modelling by using the finite element method software, and needs a sufficient analytical study to understand the causes of connecting screws loosening.

Combining finite elements modelling with the analytical approach will allow to verify the behaviour of jointed parts and gives suitable technical solutions.
