PROCESS MODELING OF INCREASING RELIABILITY OF ASSEMBLY RESPONSIBLE CONNECTIONS

Abstract

Questions of increased reliability of responsible connections at a stage of their assembly are considered in the paper. This step provides the necessary operational characteristics of outputs. The special place among such responsible connections is occupied with the group threaded connections. Their assembly technology provides reception in fixing details normalized relatively identical axial efforts in regular intervals loading a sealing layer. The presented work results of experimental research on the group threaded connection assemblage process are given. Alternate calculations of efforts change in tightened pairs of threaded connections and their graphic interpretation are presented. An algorithmic calculation model of overload factors for fixing details has been developed. Recommendations about the use of the received settlement dependences, taking into account comparative theoretical and experimental data on assembly of group threaded connection, are offered.
