A new model of the RLC vibration impact mechanism

Vibration combined with impact brings advantages to civil machines working with soils. In order to combine vibration with impact of moling machines, vibrations with compact centripetal dimension are needed. A such vibration, invented in 2007 by Nguyen et al [1-4], has attracted attentions from applied nonlinear dynamics researchers. In the former rig, the principle upon which the experimental rig is based is the combination of resonance in an RLC circuit and a solenoid, to effect impacts of a metal bar on an obstacle block. However, it should be further improved to be powerful enough for applying to actual moling machines. This paper introduces a new model of a vibro-impact mechanism which is more powerful than the former. The new mechanism is also based on the resonance in an RLC circuit and a solenoid, but to effect vibration and impacts of the solenoid instead. Experimental study shows that the new design can cause the progression rate to increase as much as 6 times compared to the former design.
