In the paper modelling and calculations of an asymmetrical bolted flange connection at the operational stage are presented. The physical model of the joint is based on a flexible flange element that is connected with a rigid support by means of hybrid elements, which substitute bolts. Between the flange element and the support, the nonlinear Winkler model of a contact layer is taken into consideration. A computational model of the system is proposed, which makes it possible to analyze any preloaded bolted flange connection subjected to an eccentric normal load. Results obtained from the calculations are compared with described experimental research.

W pracy przedstawiono modelowanie i obliczenia asymetrycznego kołnierzowego połączenia śrubowego w stanie eksploatacyjnym. Model fizyczny połączenia jest zbudowany z odkształcalnego kołnierza mocowanego do nieodkształcalnej ostoi za pomocą elementów hybrydowych, modelujących śruby. Pomiędzy elementami łączonymi wprowadzono nieliniową warstwę sprężystą typu winklerowskiego. Zaproponowano model połączenia umożliwiającego analizę dowolnego kołnierzowego połączenia śrubowego, wstępnie naprężonego i obciążonego zewnętrznie mimośrodowo siłą normalną. Uzyskane wyniki obliczeń porównano z wynikami wykonanych badań doświadczalnych.
