Abstract

To ensure the safety of high-speed railway, the temperature variations of overhead contact system (OCS) is crucial. This paper simulated and analyzed the temperature variations of dropper clip in OCS by using finite element analysis. Firstly, a 3D clamp with contact wire, electrical connection, and dropper clip is modeled on the platform of Solidworks, and its finite element model is set up by adopting HyperMesh. Next, the transient heat transmission of this model is analyzed in the environment of ANSYS by considering different temperatures of the electrical connecting clamp and external conditions. With the analysis of simulation results, the relations between the temperatures of the dropper clip and electrical connecting clamp are discussed. Since the temperature of dropper clip can be easily detected in practical applications, the temperature of electrical connecting clamp under different conditions can be found out accordingly.
