Abstract
The paper proposes a methodology to calculate indicators of the process of tightening threaded joints using impact wrenches. Such indicators include the “moment – number impacts” diagram, and the limiting tightening torque. Calculations consider the elastic-friction properties of the joint itself and the energy of single impact by the wrench. Having no data on wrench energy, we provide a method to measure it indirectly in production conditions based on the proposed methodology. The computing algorithm has produced accuracy level sufficient for engineering calculations (at least 10%) in the course of tests. The resulting methodology reduces bolt driver calibration time and improves accuracy of assembly manipulations; it also identifies the area of rational use of available assembly tools. The above aspects are particularly relevant when critical joints are assembled.
