The Exploratory Development of the Three-Dimensional Dynamic Antiresonant Vibration Isolator for Rotary-Wing Application

Abstract

The report contains the results of the experimental testing of the three-dimensional Dynamic Antiresonant Vibration Isolator (DAVI). A preliminary three-dimensional DAVI model was tested on a 'Zero-Friction' test rig. This test consisted of an isolation survey from 5 cps to 20 cps with the vibratory excitation applied independently in the three orthoganal axes. The results of the test showed that the three-dimensional DAVI model exhibited the characteristic DAVI transmissibility versus frequency curve along each of its principal axes. An improved three-dimensional DAVI model was designed and four models were fabricated. These models were installed on a platform and tested for an isolated platform weight of 60 and 160 pounds and for four different directions of excitation.
