NONLINEAR OSCILLATIONS OF DIESEL ENGINE POWER MINIPLANT
АнотаціяThe method for calculation of resonance nonlinear torsional vibrations in diesel engine power plant is suggested. Nonlinear torsional vibrations of the generating plant, which consists of diesel engine 3TD-4 and traction alternator, are investigated. As follows from the results of the calculations, a torsional resonance between braking moment of the generator and the engine transmission can occur. Therefore, the resonance vibrations must be tuned out.
