Here, one verifies the interactions between the dynamics of the DC motor (excitation) and the dynamics of the foundation (spring, damper, and mass). We remarked that we consider cubic nonlinearity (spring) and quadratic nonlinearity (DC motor) of the same order of magnitude according to experimental results. Both analytical and numerical results that we have obtained had good agreement.841-847engnonideal vibrationssommerfeld effectanalytical solutionArtigo10.1007/s11071-007-9232-3WOS:000250582100010Acesso restrito
