Single Reference Transfer Path Analysis and Airborne Structure

LMS Test.Lab Single Reference Transfer Path Analysis helps engineers trace the flow of vibro-acoustic energy from a source, through a set of known airborne and structure-borne pathways, to a given receiver location. The solution supports contribution analysis for single source noise or vibration issues, during stationary or run-up and run-down operating conditions. Airborne and structure-borne paths can be analyzed together or separately, using frequency response functions and operational data. The LMS Test.Lab Single Reference Transfer Path Analysis solution includes LMS Test.Lab’ s very convenient workflow. At each stage of the process, clear user-feedback is given. The source-transfer-receiver model is deployed in a very flexible way, with different data sets that can be easily compared against each other for the different operating cases under investigation. Operational forces can be accurately defined using the complex stiffness and matrix inversion methods. The complex stiffness method is used to identify transfer paths in cases where the source side is connected to the receiver via mounts. The operational forces can be determined from knowledge of the complex dynamic mount stiffness and the differential displacement over the mount during operation. The matrix inversion method is used to identify operational loads when the stiffness curve is unknown or for rigid connections. The technique is based on inversion of a measured accelerance matrix between structural responses on the receiver side due to force excitation. LMS Test.Lab Airborne Source Quantification ( ASQ) quantifies acoustic source strengths and their airborne transmission paths under stationary or run-up and run-down operating conditions. The method helps quantify operational acoustical loads from single point sources, multi-point sources, or even multiple partially correlated acoustical sources. Multiple techniques are supported: point-to-point surface sampling, sound intensity measurements and matrix inversion. The solution supports also the quantification of vibration loads, separately or at the same time. Acoustical Transfer Functions are measured using volume velocity source excitation techniques. Throughout the entire application, display layouts will automatically switch to layouts specific for the data evaluation at hand. The solution helps engineers easily manage vast amounts of analysis data.
