A method for calculating forced oscillations of essentially non-linear piecewise linear systems at super-harmonic resonances is proposed. The basis of this method is a combination of non-linear normal forms and the Rauscher method, by which a non-autonomous dynamic system is reduced to an equivalent autonomous system. With the help of the proposed method, super-harmonic oscillations are investigated in the power train section of an internal combustion engine. Properties of resonant oscillations are considered in detail.


Keywords: super-harmonic resonances, Rauscher method, non-linear normal forms, configuration space
