Modeling of Pantograph-Catenary dynamic stability
The purpose of this paper is to describe the possibilities of studying the influence of forces external variables on the stability of motion of dynamical systems modeled by systems of differential equations with periodic coefficients of stability. The method is applied to analyze the influence of external harmonic forces on the stability of motion of the pantograph couple contact wire electric ...
متن کاملPantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms
Contacts between pantograph and catenary are the most critical parts in the transmission of electrical energy for modern high-speed trains. Contact wire oscillations change combined force between pantograph and catenary, and the contact may even get lost. Therefore special pantographs and catenaries have been developed and further constructive changes are under development. A design criterion i...
متن کاملThe simulation of pantograph and catenary: a PDAE approach
Recently, the coupled dynamical simulation of pantograph and catenary in high speed trains has found much interest. The equations of motion form a partial diierential-algebraic equation (PDAE) that combines a partial diierential equation (PDE) for the catenary and a diierential-algebraic equation (DAE) for the pantograph. In the present paper we discuss the relation of this PDAE model to curren...
متن کاملA Three-Dimensional Calculation for Dynamic Pantograph-Catenary Interaction
Dynamic pantograph-catenary interaction is one of the most critical aspects to consider in catenary design, especially in high-speed rails. It is essential to maintain a constant power transmission in order to achieve high speeds and avoid the production of electric arcs, which damage the wires. This paper shows a tool, called InDiCa 3D, based on a three-dimensional model to solve the dynamic p...
متن کاملNon-destructive analysis (NDT) of pantograph and catenary interaction
In the last decades the development of very high speed trains in railway transportation requires new maintenance strategies. New trolleys equipped with innovative measuring systems have been employed for monitoring overhead lines (catenaries). Using this system gives two great advantages: i) the diagnose can be performed with a low level of breaking in railway traffic; ii) the monitoring can be...
