Comparison between finite element predicted and measured natural frequencies.
| | Modes | Finite element predicted natural frequency (Hz) | Measured natural frequency (Hz) | Percentage difference |
| | First mode (flexural mode of the primary beam) | 59.4 | 58.0 | 2.4 | | Second mode (torsional mode of the primary beam) | 80.5 | 75.3 | 6.9 | | Third mode (flexural mode of the secondary beam) | 112.9 | 111.8 | 0.98 |
