Determining the elasticity of the contact suspension of electrified railways

In electrified railways, the reliability and efficiency of the power supply system are directly dependent on the condition of the contact suspension. Determining the elasticity of the contact suspension is one of the most critical issues, as it impacts the following: stable operation of the current collector – if the contact suspension lacks sufficient elasticity, the stable connection with the pantograph may be disrupted, leading to interruptions in the transmission of electrical energy; reliability and long service life – excessive rigidity or flexibility of the contact suspension can result in rapid wear and tear, increasing maintenance costs; adaptation to high-speed requirements – for trains operating at high speeds, the optimal elasticity of the contact suspension is crucial; otherwise, strong vibrations and contact interruptions may occur; energy efficiency – optimal elasticity helps distribute the load evenly, reduces energy losses, and improves overall efficiency. Therefore, determining and optimizing the elasticity of the contact suspension is of great importance for enhancing the efficiency and safety of railway transport. The digitization of contact suspension elasticity is a modern necessity. Digitization can be implemented through the following methods: sensors and IT devices – smart sensors capable of measuring pressure, vibrations, and bending angles can be installed to monitor the elasticity of the contact suspension in real time; laser and video analysis – high-resolution cameras and laser scanning technologies enable continuous monitoring of the deformation and condition of the contact suspension; artificial intelligence and machine learning – based on collected data, it is possible to create performance forecasts for the contact suspension and predict wear and tear processes in advance; database systems – storing the collected data on central servers and analyzing it in real time allows for the optimization of maintenance schedules. As a result of digitization, maintenance costs are reduced, potential failures are prevented, and the efficiency of electrified railways is significantly improved
