Safety detection of locomotive axle box vibration trajectory: significance, current situation, problems and prospects

With the development of modern transportation, high-speed trains have become one of the main ways for people to travel, and the performance of locomotives as the core parts of high-speed trains is directly related to the safety and economy of the entire train. The locomotive axle box is one of the key components of the locomotive. Its function is to support the wheelset to bear external loads and to withstand intense movement and vibration. For a long time, the quality detection of the axle box has been an important content and research hotspot for the maintenance of the wheel and axle system. Therefore, the research on the safety detection of locomotive axle box vibration tracks has important practical significance and research value.

The significance of the safety detection of locomotive axle box vibration track

• Improve the effectiveness of axle box detection： With the development of the times and the advancement of technology, the detection technology of locomotive axle boxes has been continuously updated and improved to improve the effectiveness of axle box detection. Manual detection alone can no longer meet the requirements of precision and accuracy. The introduction of modern CNC detection systems can accurately measure the movement state of the axle box and form data, thereby improving the effectiveness and reliability of detection.
• Ensure the safety of train driving： The axle box, the core component of the locomotive, plays a vital role in the safety of the train. Once the axle box has safety hazards, it may cause an accident to the train. Therefore, the locomotive axle box vibration track safety detection is an important technical means to ensure the safety of train driving, which can continuously improve the safety of locomotives.
• Save locomotive maintenance costs： Traditional axle box detection requires a lot of manpower, low efficiency and poor accuracy. It is necessary to explore and study technical means that may reduce invalid costs. The introduction of digital technology breaks the traditional detection method, which can not only quickly and accurately detect axle boxes but also greatly reduce labor maintenance costs and significantly improve detection efficiency.

Research status of locomotive axle box vibration track safety detection

With the continuous advancement of wheel axle technology and the development of modern science and technology, Chinese and foreign scholars have conducted research on locomotive axle box vibration track safety detection from different angles and levels, aiming to build a more scientific and effective detection technology system.

• Vibration and noise diagnosis technology of locomotive axle box：The research on locating axle box faults using vibration response signals can quickly detect vibration faults in high-speed vehicles, providing a theoretical basis for subsequent improvement of detection.
• Non-destructive testing technology： The application of non-destructive testing technology to the axle box can effectively detect the internal faults of the axle box, such as surface cracks, insufficient strength and other problems, and improve the reliability and safety of the axle box. A typical example in this regard is the application of ultrasonic flaw detection technology.
• Digital detection technology： Through the method of external force excitation of the axle box and image acquisition, fine analysis and data integration of the axle box, the comprehensive and accurate detection of the vibration track of the locomotive axle box can be achieved, providing technical support for the latter locomotive maintenance.Digital detection technology.

Problems in the safety detection of the locomotive axle box vibration track

• Lack of unified detection standards：At present, there is no unified detection standard for the detection track of the locomotive axle box at home and abroad. Different detection standards have different expressions, detection methods and parameter evaluation methods for near and far problems, and there may be certain problems in practical applications.
• The cost of detection equipment is too high： For many small and medium-sized railway operating companies, the purchase of high-end locomotive axle box vibration track detection equipment has repeatedly exceeded the financial capacity. Therefore, it is necessary to explore more flexible and low-cost detection technologies continuously.
• Data processing technology still needs to be improved. In terms of digital detection technology, the processing of detection data is also an indispensable part. However, limitations in data processing technology have hindered some companies from using digital detection technology.

Prospects for locomotive axle box vibration track safety detection

In order to further improve the detection efficiency and accuracy of locomotive axle boxes, it is necessary to continue to strengthen technical research and development to achieve better axle box detection. At the same time, matching the detection equipment suitable for oneself is also one of the important factors

• Improve the data processing capacity of the locomotive axle box and use target axle box identification and self-developed algorithm detection technology.
• Carry out the work of international standardization of locomotive axle box detection technology and promote mutual certification of various international standards.
• Strengthen the training of talents in locomotive axle box vibration track detection technology and improve the quality and professional ability of talents.

With the continuous development and improvement of locomotive axle box vibration track safety detection technology, not only improves the effectiveness and accuracy of detection but also provides important guarantees for railway transportation safety. In future development, professionals in this field must continue to work hard and constantly innovate to meet higher safety requirements and economic goals.
