Multiple vibratory sources are integrated in the aircraft and rotorcraft. The vibrational power of these sources is injected to the receiving structure through their connection points resulting in annoying acoustic levels in the cabin. This noise, referred to as structure borne noise, could be mitigated if vibrating systems, receiving structures and interfaces between them are well designed. Methods such as Reception Plate Method (RPM) and Component-Based Transfer Path Analysis (CB-TPA) have been developed to specify proper design guidelines related to noise mitigation during the design phase. This paper focuses on the CB-TPA. The main advantage of this method is to predict the vibratory behavior of an assembly (source and receiving structure) from the intrinsic properties of its subsystems. Nevertheless, it is not straightforward to assess these properties because of several experimental difficulties such as the completeness of the mobility matrices, a passive property required for both subsystems. The objective of this work is to assess the experimental applicability of two CBTPA methods on a small scale laboratory setup comprising of a controlled vibratory source mounted onto a flat panel. Two controlled vibratory sources with more or less complex vibratory behaviors have been designed in order to assess the CB-TPA methods sensitivity to matrices incompleteness. Passive and active properties of subsystems are assessed, taking into account 3 translational degrees of freedom. The vibratory response of the assembly generated by the source coupled to the plate is estimated and the impact of the completeness of the subsystem's characterization is discussed.
