Development of the Physical Simulation Platform for Catenary Cantilever

Regarding to the problem of deviations in the cantilever pre-assembling, a physical simulation platform for cantilevers has been developed. This platform simulates the actual operating conditions of the high-speed rail pantograph-catenary and conducts simulated inspections and calculations to the pre-assembling cantilever before installation, obtaining stagger value data and predicting whether the cantilever is qualified or not. This allows for timely adjustments or re-manufacturing of the cantilever, thereby effectively reducing construction risks.

I. Introduction

Catenary is an important system of high-speed railway, which is responsible for providing electrical power to the train [1]. As seen in Fig. 1, it mainly consists of cantilever, dropper, contact wire, messenger wire, pole and etc. The train gets electrical energy from the contact wire through sliding between the train's overhead pantograph and the contact wire. So, the quality of catenary directly determines the speed, stability and safety of the train [2]-[5].
