General framework for transfer path analysis: History, theory and classification of techniques ?
In this paper a general framework for Transfer Path Analysis is presented. The vibration transfer problem is derived conceptually, based on the admittances of the active and passive subsystems. Eleven methods are derived and classified into classical, component-based and transmissibility-based TPA. The evolution of historical developments to practical TPA methodologies is presented. Several practicalities are discussed that may be important when conducting a TPA.
