Sensitivity analysis of pantograph-catenary system model

The contact wire experiences a dynamic force from the pantograph mechanism which results in the vibrations in the contact wire. A mathematic model between displacement of contact wire and force is developed. The displacement and dynamic force vary with the parameters of pantograph mechanism. The sensitivity analysis of pantograph model wrt parameters of interest has been carried out in this paper. Also, the time response and frequency response of close loop model of pantograph has been studied and presented.
