Table 3 Parameter settings for different multi-frequency excitations.
Forms of excitations | Excitation frequency (Hz) | Excitation amplitude (N) | Phase |
|---|---|---|---|
Dense excitations | \(f_{{F_{1} }}\) = 88.0; \(f_{{F_{2} }}\) = 94.0; | \(F_{1} = F_{2}\) = 1.0 | \(\phi_{1} = \phi_{2}\) = 0 |
Non-dense excitations | \(f_{{F_{1} }}\) = 85.0; \(f_{{F_{2} }}\) = 95.0; | \(F_{1} = F_{2}\) = 1.0 | \(\phi_{1} = \phi_{2}\) = 0 |
