From: Negative potential energy content analysis in cracked rotors whirl response
Effect of unbalance force vector angle \(\beta\) at varying shaft rotational speeds on potential energy content in steady-state response of horizontal cracked rotor system with open crack model depths \(\mu = 0.05\) in (a), \(\mu = 0.1\) in (b), \(\mu = 0.15\) in (c) and \(\mu = 0.2\) in (d).
