In this study, we investigate the oscillation phenomena in a random-coupled network of hard-type oscillatorswhose nonlinear characteristics are represented by fifth-power polynomials. Recently, we have shown that thechaotic phenomena are seen in the network with soft oscillators whose nonlinear characteristics are represented bythird-power polynomials. In this report, we show not only chaotic phenomena but also torus and random switchingphenomena of amplitudes which are not shown in the networks with soft type oscillators by changing the couplingcoefficcieients.
