Train running stability test with RE-846U system
Project name: Train Stationarity Experiment
Brief introduction：In modern rail transportation, ride comfort and operational stability remain essential indicators of both passenger satisfaction and overall equipment performance. As high-speed rail systems continue to advance rapidly, ensuring that locomotives operate smoothly and reliably under a wide range of speeds and diverse track conditions has become a crucial aspect of train development and rigorous validation processes.
To evaluate these performance metrics, CSR Zhuzhou Electric Locomotive Co., Ltd. conducted a comprehensive Train Stationarity Experiment using Dynatronic’s RE-846U Rugged Dynamic Signal Test System. This high-performance system, combined with specialized and dedicated analysis software, was carefully deployed to collect comprehensive real-time data on multiple critical operational parameters of the train throughout the live test runs.
The testing focused on capturing a wide range of physical signals, including:
Lateral and vertical acceleration of car bodies and bogies
Vibration levels across different speeds and track conditions
Axle load variations during acceleration and braking
Dynamic displacement and structural response of the frame
By utilizing the RE-846U’s advanced high-speed, multi-channel capabilities, engineers successfully recorded synchronized data streams collected from a variety of sensors strategically installed throughout the locomotive. The specially designed accompanying software then processed this extensive data, enabling the generation of detailed and comprehensive analysis reports. These reports included critical elements such as vibration curves, frequency spectra, and real-time stability assessments, providing valuable insights into the locomotive’s performance and condition.
The results allowed CSR Zhuzhou to:
Assess running smoothness at various speeds
Detect abnormal vibrations that may lead to wear or fatigue
Validate suspension and damping system performance
Optimize train design for improved comfort and safety
This project clearly demonstrated how advanced, cutting-edge dynamic testing solutions can effectively support the development of rail vehicles that are not only reliable and efficient but also comfortable for passengers, all while significantly reducing the risk of structural fatigue and minimizing long-term maintenance costs.
