Grahic Jump Location
Acoustic modes inside a cylindrical shell or structural modes of a circular disk—mode orders: p,q (acoustic), m,n (structural)
Grahic Jump Location
Coincidence conditions between structural and acoustic modes schematically—(a) diametral modes, (b) mixed diametral/circumferential modes
Grahic Jump Location
Examples of wave number coincidence between structural and acoustic waves
Grahic Jump Location
Two degrees of freedom spring mass oscillator system representing structural-acoustic interaction
Grahic Jump Location
Example of local alteration of casing of a centrifugal fan to affect harmful acoustic modes
Grahic Jump Location
Sample problem showing wave number coincidences in second diametral modes for a centrifugal fan—(a) for ωsa, complete coincidence with coupling, vibration and acoustic fatigue predicted; (b) for ωs sufficiently separated from ωa (a minimum of 25 percent), vibration not predicted
Grahic Jump Location
Sample problem showing frequency coincidence but no wave number coincidence—(a) no coupling, condition acceptable; (b) with presence of single frequency (blade passing frequency) pulsation ωBPas, forced vibration at resonance, condition not acceptable
