WebMar 14, 2024 · However, this is only true at a single frequency. In the figure below, a two-DOF system is considered. The damping values have been matched at the first resonance, and it is clear that the predictions at the second resonance differ significantly. Comparison of dynamic response for viscous damping and loss factor damping for a two-DOF system. WebApr 12, 2024 · We set all damping coefficients to 0 and adjust the value of k c until the resonance shift matches the corresponding experimental results. Second, we determine the contact damping coefficient. We assume that the damping coefficient does not affect the resonant frequency because the damping coefficient is relatively low. WebSep 12, 2024 · Resonance occurs when the driving frequency equals the natural frequency, and the greatest response is for the least amount of damping. The narrowest response is also for the least damping. It is interesting to note that the widths of the resonance curves shown in Figure \(\PageIndex{4}\) depend on damping: the less the damping, the … george h ross trump
