A parametric amplifier circuit is described. The nonlinearity involved is an abrupt one and a method of analysis of "relaxation oscillations" is preferred to techniques assuming quasi-linearity. This leads to a physical understanding of the cycle of oscillations as well as quantitative relationships

As a wheel moves along a discretely supported track, it can experience parametric excitation due to the varying dynamic stiffness of the track. In order to study this, an equivalent time-varying model is developed for the track, according to the space-varying receptance in a sleeper bay. Using this
