摘要: Abstract This paper presents the mathematical modeling and dynamical analysis to examine coupled effect of inertial mass excitation frequency on a Duffing vibro-impact device used for autogenous mobile systems. The oscillation with nonlinear spring is utilized generate impacts thus drive whole system. Forward motion observed in wide range excited ratio. interaction between system body can provide backward narrow ratio excitation. proposed model has validated by an experimental implementation, be as useful tool optimize dynamics. Bifurcation study carried out better understanding design selection parameters. dimensionless parameters allows extending results both large- micro-scale applications.
