15 years of NVH applications make Transfer Path Analysis (TPA) appear a commodity tool. But despite the fact that TPA is today widely used in a large variety of applications in automotive and mechanical industries, its main bottleneck remains the huge measurement efforts to build the full TPA model. This paper presents a new TPA approach, which provides a good compromise between path accuracy and measurement time. The method is also referred to as OPAX. The key idea of OPAX is the use of simplified parametric load models with limited number of model parameters. The advantage of this is that one should measure only a small amount of FRF data to identify the loads. This drastically reduces measurement time and efforts. Next to this, the OPAX method does not require mount stiffness data and it allows a simultaneous identification of both structural and acoustic paths. The paper first briefly reviews the main principles of OPAX and then presents the results of an extensive validation test campaign, comparing this new method with conventional TPA.
