| Abstract: | The complex dynamics characters of Josephson junction circuit are investigated by numerical simulations.The dynamics equation and the state equation of Josephson junction circuit are established according to the circuit model and Kichhoff's laws.By the phase portrait,global bifurcation diagrams and Lyapunov exponents map,the chaos forming process of the system is studied under the presented system parameters.This provides straight clue to avoid chaos and valuable information for stable operation in Josephson junction devices. |

| Keywords: | Josephson junction bifurcation diagrams Lyapunov exponents period-doubling bifurcation |
