Description
Summary:The swift progression in the automotive sector has spurred the demand for electric power-assisted steering systems, heralding a transformation towards a more effortless, fluid, and pleasurable driving experience. However, the inherent generation of substantial noise levels within the vehicle’s cabin during the operation of these systems, can compromise the comfort of occupants, underscoring the criticality of acoustics analysis in the advancement of auxiliary systems. As long-established tools for Noise, Vibration, and Harshness (NVH) diagnostics, Transfer Path Analysis (TPA) techniques are central to studying noise propagation within vehicles. Component-based TPA, with its strength in identifying interface forces in mechanical structures, has gained a foothold in the industry due to its numerous advantages. We aim to shed light on the individual acoustic properties of the electric motor, thereby gaining a more nuanced understanding of the system’s behavior. We first lay out a brief theoretical background on relevant TPA methods, followed by the presentation of our findings from experimental studies. This paper continues our commitment to advancing the precision and practical use of TPA methodologies in automotive system analysis.
