The article discusses the developed complex for obtaining objective information during fatigue testing of crankshafts of autotractor equipment with a pure bend in the plane of the crank under dynamic loading on a resonant stand. The data for its implementation and the test results of crankshafts 24–1005011–20 produced by ZMZ OJSC are presented.
