A Study on Improvement of Vibration Performance of Air Damping Bush Using Fluid-Structure Interaction Analysis

Abstract— Because the three-point engine mount among the air damping engine mount has excellent performance, many studies have been carried out. However, studies on the high damping roll mount have been demanded because of the high contribution rate of the interior noise of the roll mount. In this study, the vibration characteristics for the basic design model of the engine mount according to each case were examined through the fluid-structure interaction analysis applying the trial & error method and the optimal design that can increase the damping effect is suggested. In order to examine the damping effect of the air damping engine mount, five design model including the initial model were reviewed. It was confirmed that the damping effect when the system stability is considered is the largest in final change model in which the stopper is removed from the reviewed design model. The optimum model of air damping bushing is proposed through this study to improve vibration performance.
