Abstract. -We consider a model of Josephson junction driven by a two-frequency quasiperiodic field. In dependence on the amplitude of one frequency component, the transition from a state with zero average voltage to that with a nonzero voltage occurs via the appearance of an intermittent regime, represented either by a smooth torus, or by a strange nonchaotic attractor. The intermediate
