How to determine natural frequency from graph

WebJan 20, 2024 · Frequency response. The frequency response of a system is the relationship between the frequency of the measured waves and the amount of amplitude amplification which might occur as the result of resonance. It can be represented on an amplitude/frequency graph: From this, the beneficial effects of damping become clear. WebKeep the natural frequency fixed. Run the program for different excitation frequencies. Watch what the system is doing. Observe the behavior when the excitation frequency coincides with the natural frequency of the system. Try this test for each type of excitation.
