Analysis of Tubular Visco-Elastic Suspension Based Vibration Isolation in Wheeled Construction Vehicles

In order to improve the vibration-isolation of wheeled construction vehicle, a new type of tubular visco-elastic suspension is proposed in this paper. A half vehicle mathematical model is used to simulate the dynamics of wheeled construction vehicle in its vertical direction. To obtain vibration-buffering properties of the proposed tubular visco-elastic suspension, four different ground profiles are applied as inputs to the model. The vertical accelerations and displacements are analyzed between the tubular visco-elastic suspension and traditional rigid suspension. The analysis results show that the vibration level is decreased by the use of tubular visco-elastic suspension.
