WebApr 30, 2024 · The nonlinear vibration also has no effect on Q factor in the literature in the case of the thickness of 1.5 μm and the amplitude range of less than 40 nm (Inomata et al. 2016). A much thinner nanomechanical resonator is thought to have a more significant effect of amplitude on Q factor. WebVery high damping produces a very boring SRS: A horizontal line. The level of damping is demonstrated by the "quality factor", Q which can also be thought of transmissibility in sinusoidal vibration case. Relative damping of 5% results in a Q of 10. An SRS plot is incomplete if it doesn't specify the assumed Q value.
