چکیده
In the automotive industry, noise, vibration, and harshness (NVH) are critical factors affecting vehicle comfort and performance. Constrained Layer Damping (CLD) has emerged as an effective technique to mitigate these issues by dissipating vibrational energy. The Oberst Beam Method (OBM) is a widely used experimental technique for measuring the loss factor of materials, a vital parameter in assessing the effectiveness of CLD systems. This paper aims to review the theoretical foundations and experimental procedures of the OBM, compare it with other measurement methods, discuss its applications in automotive engineering, recent advancements in measurement techniques, challenges faced in practical applications, and future research directions. By synthesizing current knowledge, this review highlights the significance of the OBM in enhancing CLD performance and offers insights for further developments in this field.
