The purpose of this paper is to reduce vibration and noise in the tractor cabin using a mass damper actuator. First, in the tractor cabin, vibration and noise are measured and the contribution ratio of solid born noise, that can be decreased, is investigated. Next the control effectiveness of the active mass damper is understood, and the active control system is designed based on velocity feedback...
The purpose of this paper is to predict vibration response of the parts in a tractor cabin in engine-idling status using Statistical Energy Analysis (SEA). First, modeal density and loss factor of each part is estimated, and it was found that modal density of plane parts is constant regardless of frequency, while that of complex parts changes with frequency. Then, vibration response was calculated...
