Pantograph is one of the key components of electric train systems, responsible for transferring electrical current from the overhead contact wires to the locomotive. This component, particularly its carbon strip, is in constant contact with the overhead wire an‎d, as a result, undergoes wear an‎d damage due to friction, mechanical impacts, an‎d temperature variations. Such damages can negatively affect the performance of the electric train system, leading to reduced power transmission efficiency, increased maintenance costs, an‎d even serious accidents. One of the effective solutions to prevent these problems is the condition monitoring of the pantograph’s carbon strip. In this regard, simulating the contact between the carbon strip an‎d the overhead wire has attracted attention as a laboratory tool. In this project, a simulator device is designed an‎d built to replicate the contact between the pantograph strip an‎d the overhead wire. The main goal of constructing this device is to fulfill the requirements an‎d characteristics necessary to simulate the carbon strip–overhead wire interaction as close as possible to real operational conditions. These requirements include reproducing the zigzag motion of the overhead wire relative to the carbon strip, replicating the contact force between the panhead an‎d the overhead wire similar to actual conditions, an‎d simulating the suspension system between the pantograph head an‎d its upper arms in a realistic manner. The carbon strips are mounted on the pantograph head (panhead). By installing accelerometer sensors on the pantograph head in the test device, acceleration data are recorded an‎d subsequently analyzed. This project has been designed with the aim of eva‎luating the feasibility of monitoring the condition of the pantograph’s carbon strip using the data obtained from accelerometer sensors mounted on the pantograph head. The use of these sensors enables precise recording an‎d analysis of vibrations caused by wear an‎d potential damages.
