Effects of nonlinearity of a contact layer between elements joined in a multi-bolted connection on preload values in bolts
Journal Title: Bulletin of the Military University of Technology - Year 2014, Vol 63, Issue 1
Abstract
In the paper, modelling and calculations of an asymmetrical multi-bolted flange connection atthe assembly stage are presented. A physical model of the joint is based on a flexible flange element that is connected with a rigid support by means of linear spring elements which substitute bolts. Between the flange element and the support, the linear Winkler model of a contact layer is taken into consideration. Through example of a few multi-bolted connections, influence of nonlinearity of the contact layer between joined elements on computational values of the bolt preloads has been investigated. Results obtained from the calculations are compared with experimental results described in [1].[b]Keywords[/b]: multi-bolted connections, assembly condition, preload
