The authors have developed a synchronous vibration mechanism for a tamping rammer used to compact cohesive soils and asphalt. This system consists of three mass-blocks coupled by springs, and the rotor-type oscillators are mounted individually on the lower blocks. The nonlinearity due to the impact behavior between the lower blocks and a ground is approximated by piecewise linear characteristics. In this report, the self-synchronized solutions and its stability are analyzed by applying the improved shooting method for impact vibration analysis. The results confirmed that the self-synchronized solution which can achieve a good balance between utilization of vibration and vibration control exists in the present system.
