Low Cost Catenary Design-Analysis. Final Report, Task 1 and 2

摘要

A new system of railroad electrification has been studied that requires only a single contact conductor as opposed to the conventional catenary system. Preliminary designs for the various components have been developed and are described. These include the traveller (that rides on the contact conductor), the traveller arm and the supports for the contact conductor. Various dynamic analysis models were developed including a six-degree of freedom model and finite-element model to study the dynamic performance of the total system. Results of the interaction of the components are presented for various contact conductor diameters and tensions, for different span lengths between supports and for various vehicle (traveller) speeds. These results indicate the concept is feasible and the design is viable. Further, the report recommends that the full-scale field test (tasks 3 to 7 inclusive of the contract) be funded to complete the dynamic analysis and to provide a working mechanical model.
