  We present an extensive study of the effects of quenched disorder on the
dynamic phase transitions of kinetic spin models in two dimensions. We
undertake a numerical experiment performing Monte Carlo simulations of the
square-lattice random-bond Ising and Blume-Capel models under a periodically
oscillating magnetic field. For the case of the Blume-Capel model we analyze
the universality principles of the dynamic disordered-induced continuous
transition at the low-temperature regime of the phase diagram. A detailed
finite-size scaling analysis indicates that both nonequilibrium phase
transitions belong to the universality class of the corresponding equilibrium
random Ising model.
