The purpose of this study was to develop, test, and analyze the Dynamic Vibration Resonator (DVR), a spring-mass device which attaches between exhaust pipes and serves to reduce "cabin drone" in vehicles. The DVR was lab and field tested and shown to effectively attenuate vibrations in two important frequency ranges: 164-167 Hz and 183-188 Hz. A generalized vibration model of the DVR was formulated and used to determine the contribution of DVR components, of which the central mass geometry, main carrier rod and brackets were identified as being critical to vibrational response. Finite element analysis (FEA) was used to predict the natural frequencies of the DVR and correlated within 5% error to experimental measurements. A fully parametric CAD model of the DVR and Fortran solution code for solving the vibration equations are presented.
