On the Estimation of Structural Admittances from Near-Field Acoustic Holography Using a Dynamic Sub Reconstructing structural admittance based on normal velocity establishes NAH as alternative to the conventional methods such as accelerometers or laser vibrometers. Measuring vibrating object using microphone array offers high-resolution measurements and with this the possibility to obtain spatial

Weakening of the Interface Constraints in Modal Substructuring Using Singular Value Decomposition,onstrain equations to be applied when considering an interface with multiple connection points. An approach to solving this problem was presented in the transmission simulator method (TSM), where a truncated set of mode shapes of a flexible fixture is used to project the constraints on the fixture’s

Introducing pyFBS: An Open-Source Python Package for Frequency Based Substructuring and Transfer Pang. State-of-the-art methodologies in frequency based substructuring, such as virtual point transformation and system equivalent model mixing, are available within the pyFBS. Each method can be used as a standalone or interchangeably with others. Tools are provided to easily visualize components and

Analysis of Friction Induced Mode Coupling Instabilities Using Dynamic Substructuring,hen different parts of the system move one with respect to the other generating friction force at the contact interface. Component mode synthesis and more in general substructuring techniques represent a useful and widespread tool to investigate the dynamic behavior of complex systems, but classical

Road Noise: Embedding Suspension Test Benches in Sound & Vibration Design using virtual points and these results to full-vehicle assemblies is not immediately possible because of the difference in boundary conditions and incompatibility between test bench and vehicle measurement points..This study focuses on the use of tire noise test benches in the engineering of full-vehicle NVH. We show how vi

On Predicting Uncertainties in the Dynamic Response of a Welded Structure,ends not only on the components that it is made of, but also equally on the joints. Joints determine how the components interact within a structure, making validating the models for joints as important as validating the subcomponents. A joint does not physically exist on its own but co-exists with t
