摘      要：The original article includes the incorrectly printed Figs.1,2 and *** correct figures are included in this ***.1.(a)Experimental setup:The shaker is used to generate the external,harmonic and random excitation to the base of the metal *** resulting oscillations are measured with a strain gauge.A nonlinear restoring force follows from the magnets mounted at the cantilever tip and the fixed frame.(b)Measured cantilever response to sinusoidal excitation and experimental procedure:A sweep up is used to realize the high amplitude *** the excitation frequency reaches 39.6 Hz,noise is added to the input and a noise induced escape is observed.(c)Time series of a strain gauge signal:The forcing frequency is 39.6 Hz and the response is initiated in the high energy *** about 37.0 s an escape towards the low amplitude orbit is observed.
