Abstract

The description of the oscillatory dynamics of the discrete-continuous system over-head catenary suspension-electric rolling stock pantograph is reduced to the Mathieu equation with a periodic external influence. Analytical expressions for combinations of parameters of an actual catenary suspension and an actual pantograph, whose variation changes the effective properties of the pantograph, are obtained. The opportunity of theoretically selecting optimum combinations of properties of an actual pantograph and an actual catenary suspension expands the methods of purposeful suppression of undesirable self-oscillatory modes directly in the course of electric rolling stock movement and allows pantograph dependability to be improved.
