FIELD: machine building.
SUBSTANCE: according to present method components of analysed group of threaded connections are determined by analysis of model. Further, the first group of threaded connections in an analysed group is subjected to physical tests. There is performed modelling analysis of the first and second groups of threaded connections. Physical tests are not carried out for the second group. After modelling results of a physical test and modelling analysis are compared to obtain a factor of working characteristic for the first group. Further, the factor of the working characteristic is applied for the second group and limits of functionality are determined on base of this factor of the working characteristic.
EFFECT: increased reliability of threaded connections.
