Abstract

Vibration analysis is a prerequisite for design and diagnosis of rotating machinery. Most vibrations in rotating machinery are induced by rotation-related sources: rotating unbalance is the major source of vibration synchronous to the rotational speed (Ω); misalignment and cracks in shafts cause the vibration of frequency iΩ (i is an integer); ball bearing defects cause vibration with frequency nΩ (n is a real number), and so forth [1–6]. Thus, forced vibration analysis of rotating equipment subject to asynchronous harmonic excitation is essential for identifying the vibration sources or ensuring proper design of the equipment.
