Abstract

This paper starts with dynamic response of pantograph slider, and computes the dynamic parameters of pantograph-catenary system such as contact force, hard spot, pull-off value and contact wire height by utilizing the transfer function matrix gained beforehand and the displacements of pantograph slider measured with the laser range sensors configured at the low voltage side. The paper also deducts the numerical algorithm of response matrix and transfer function matrix, demonstrates the feasibility of reducing the number of laser range sensors, and verifies its effectiveness by simulation with a simple example.
