Modelling of transverse vibrations and stability analysis of the wheel pair with the curvilinear profile of the roll surface

The mathematical model of transverse vibrations of a wheel pair is considered. This model is adapted to the curvilinear profile of the roll surface of the wheel described by the second-order multinomial. The obtained mathematical model takes into account the restoring (gravitational) force. Taking into account the dependence of restoring force from the coefficient of the equation squared term of the profile the authors investigate the transverse motion stability of the wheel pair.
Keywords: wheel pair, profile, motion, model, restoring force, Hurwitz determinant, subdeterminant, stability

On the issue of connection of overvoltage limiters to the contact network

The authors consider the operation features of overvoltage limiters connected to the contact network through horn arresters, shunted by copper wires. It is shown that the wires can be destroyed by electrodynamic forces from the induced overvoltage. The damage of the shunting wires leads to deterioration of the protective properties of the overvoltage limiters from overvoltage of subsequent lightning components.
