Abstract
The approach for calculation of nonlinear normal modes (NNM) of essential nonlinear piecewise linear systems’ forced vibrations is suggested. The combination of the Shaw–Pierre NNMs and the Rauscher method is the basis of this approach. Using this approach, the nonautonomous piecewise linear system is transformed into autonomous one. The Shaw–Pierre NNMs are calculated for this autonomous system. Torsional vibrations of internal combustion engine power plant are analyzed using these NNMs.
