Resonance and Absorption
Harmonic excitation often occurs in engineering systems. It is commonly produced by the unbalance in machines with rotating parts. Further, understanding the behavior of a system with harmonic excitation is an essential indication how the system will respond to more general types of excitation. Therefore, for system analysis the frequency response introduced in Chapter 5 has to be investigated in more detail. This investigation yields a theory of resonance and absorption affecting the design of vibration system little sensitive to excitations, the tuning of vibration absorbers, the contraction of vibration measuring instruments, etc.
