Summary:

AbstractOperational Transfer Path Analysis (OTPA) assess the possible ways of energy to transfer from the various sources of excitation to a given target location. Applied to vehicle engineering, the OTPA provides indication about dominant sources and path contributions. However, it can only analyze the actual system under test and cannot predict if an improvement can be achieved by applying a counter measure. A careful interpretation of the measurement results is therefore necessary in order to define an effective engineering solution strategy.In this paper the RMA (Response Modification Analysis) technique is used to facilitate a sensitivity analysis, gaining insight whether energy is likely to be rerouted. This gives additional understanding of OTPA results, indicating which counter measure is most effective. The RMA is applied to a real measurement scenario, showing the advantage of the combination of OTPA with RMA for correctly identifying the relevant sources and paths
