Prediction of Power Flows Through Machine Vibration Isolators

Power Flow Analysis of Complex Coupled Systems by Progressive Approaches

“…This is often used as the cost function minimized to assess vibration control [20,21,38,39]. Therefore, the transmitted forces F and velocity responses V at the N mounting points as well as the total power #ow P transmitted to the supporting foundation through the N anti-vibration mountings are presented here to illustrate the dynamic characteristics of the chosen #oating raft vibration isolation system.…”

“…The transmission of vibratory power #ow from a vibrating rigid body into a thin supported panel through two mounts was investigated by Pan et al [20]. Li et al [21] studied a more complex case concerning the transmission of vibration power #ow from a vibrating rigid machine into a rectangular plate with a number of reinforcing beams placed in any directions. Li et al [22] studied power #ow for a simple #oating beam-like raft isolation system with one machine subject to a single harmonic force excitation using a Green function.…”

Vibrational Power Transmission From a Machine to Its Supporting Cylindrical Shell

“…being a transformation matrix whose elements are simply the direction cosines of the principal axes [10]. The (reaction) forces at each mounting point can be easily transferred to the CG of the rigid body, that is,…”

Vibratory Power Flow Analysis of a Gear‐Housing‐Foundation Coupled System

“…Petersson [26] addressed the need to consider both the multimount and the multidirectional vibration transmission in the analysis. Li [27] compared the transmitted reaction force and power flow in an isolator system and pointed out that power flow is more reasonable as a performance index especially at high frequencies. Weng [28] and Sun [29] studied the relationship between power flow transmissibility and vibration acceleration level difference.…”
