The bent beam is formed by two spring segments perpendicular to each other, joined at the corner of the central mass as shown in the picture. The two segments of the beam can have different length, but is assumed to be equal. The mass is suspended on four such bent beams. A typical structure is as shown above.
This design interface can be used to determine the natural vibration frequency of a bent beam suspension. The vibration frequency for the lowest vibration mode can be estimated. The first mode would move the mass perpendicular to its plane in Z axis.
The plot shows the amplitude frequency relationship for the given suspension for the first mode. It shows the first resonance frequency as a sharp rise in amplitude. Using the cross hair tool, the resonant frequency and the corresponding relative amplitude can be obtained.
