The impact of mass ratio $\lambda$ on the self-translation system. The remaining system parameters are configured as follows: ${\overline{I}}_0=0.6$, $\overline{C}=0.3$, $\overline{\delta }=0.25$, ${\mu }_1=0.01$, $R=1.8$, $\overline{K}=3.8$, $\overline{\beta }=0.08$, $\overline{g}=2.0,$ and ${\overline{v}}_0=0.5$. (a) The limiting circle of the mass ball. (b) Displacement–time curves of the slider. (c) The amplitude and frequency of self-oscillation. (d) The average velocity of self-translation. As the mass ratio increased, it was noticeable that the amplitude $A$ remained relatively constant, while the frequency $f$ and the ${\overline{v}}_a$ of the slider’s self-translation decreased.
