Исследование напряженного состояния и герметичности арматурных фланцевых соединений

Abstract

The present work carries out research tensely-deformed conditions and tightness reinforcing flanged connections. In work the mode of installation and a working condition are considered. At statement of a problem it is considered two contact pairs: connections of nuts and a flange, and also a lining with flanges. The lining was modeled by the task of nonlinear characteristics of a material on the basis of experimental data. Calculati on is made with the help of the program complex, based on a method of final elements. Comparison of results of calculation with the results received by the approached technique, developed "UKRNIICHIMMASH" is given.
