Figure 3.

The eigenfrequencies of a perpendicular gyroscope system with a clamped base, as functions of the gyricity. The analytical solution (solid lines) has been overlaid with the results from the two finite element models discussed in §5, demonstrating the agreement of the three models. The crosses indicate the eigenfrequency solutions from the finite element model with the CTBCs applied at the tip of the Z-beam. The dots indicate the eigenfrequency solutions for the finite element model with the Ex-CTBCs applied to the tip of the X-beam. The avoided crossings of the first and second, then second and third eigenfrequency branches are shown inset.
