Nonlinear normal modes of essentially nonlinear piecewise-linear systems under periodic excitation (English)
0 references
The authors propose a method for the calculation of nonlinear normal modes of essentially nonlinear piecewise-linear systems under forced oscillations. The approach is based on the combination of nonlinear normal Shaw-Pierre modes and the Rausher technique. By means of this approach, the non-autonomous piecewise-linear system is transformed into an autonomous one. In this system the nonlinear normal Shaw-Pierre modes are determined. The proposed method is used for the analysis of nonlinear torsional oscillations of power transmission in transport three-cylinder engine.
