Ningbo University Uses A Bearing Life And Fault Diagnosis Simulator for Undergraduate Teaching

Recently, Ningbo University has made significant progress in the procurement of research and teaching equipment. Valenian's BTS200 rolling bearing lifecycle prediction and maintenance system, as well as PT700 electromechanical equipment health assessment and fault diagnosis comprehensive test bench, have been successfully delivered. The introduction of these two devices will greatly enhance the research level and teaching quality of the school in related fields such as mechanical engineering and equipment maintenance.

Background and significance of procurement

With the rapid development of technology, there is an increasing demand for reliability and maintenance efficiency of electromechanical equipment. Ningbo University has always been committed to cultivating professional talents that meet the needs of the times and conducting cutting-edge scientific research work. As a key component widely used in mechanical equipment, rolling bearings have a direct impact on the performance and lifespan of the entire device in terms of their operating status. The procurement of the BTS200 rolling bearing full life cycle prediction and maintenance system aims to achieve full process management of rolling bearings from operation monitoring to fault prediction through advanced technological means, detect potential problems in advance, reduce equipment failure risks, and improve overall equipment reliability.

The PT700 comprehensive test bench for health assessment and fault diagnosis of electromechanical equipment provides a comprehensive experimental platform for schools, which can simulate the operating conditions of various electromechanical equipment, comprehensively evaluate the health status of the equipment, and carry out research and teaching practices related to fault diagnosis. This is of great significance for enhancing students' practical abilities and promoting the development of related scientific research projects.

Functional characteristics of BTS200 rolling bearing lifecycle prediction and maintenance system

The BTS200 system has powerful functions that can simulate various types of bearing life tests, including deep groove balls, cylindrical rollers, tapered rollers, angular contact balls, needle roller bearings, and more. Its design structure allows the use of various outer diameter bearing seats and bearing adapters, which can adapt to the testing needs of different sizes and types of bearings. The system is equipped with oil temperature monitoring feedback, oil level gauge, and centralized oil supply circulation system, and can set temperature alarm thresholds. At the end of the supporting bearing shaft, an additional load of up to 15000N can be applied under the rated load of the bearing. It is a professional experimental equipment used for long-term operation and testing of early bearing wear. Through this system, researchers can conduct basic research on the development process of bearing wear, conduct modeling and analysis of the damage and degradation trends of rolling bearings and bearings lubricated with grease, gain a deeper understanding of the relationship between bearing failure mechanisms and bearing loads and speeds, and develop a prediction model for bearing residual life. At the same time, it can also be used to study sensor types and signal processing techniques for bearing condition monitoring and life prediction, explore the correlation between vibration, motor current, load, friction, and noise spectra, and provide strong support for model basic diagnosis and life prediction algorithms.

Highlights of the PT700 comprehensive test bench for health assessment and fault diagnosis of electromechanical equipment

The PT700 comprehensive test bench for health assessment and fault diagnosis of electromechanical equipment also has significant advantages. In terms of motor fault simulation, through careful design, it is possible to accurately simulate motor faults, allowing users to deeply explore the root causes and effects of faults, effectively improving fault diagnosis capabilities. In gear fault simulation, it can realistically present gear fault conditions, allowing researchers to personally experience the negative effects of gear faults on mechanical operation, thereby greatly improving the accuracy of fault identification. For bearing fault simulation, this test bench can highly reproduce bearing fault scenarios, helping university personnel to clearly grasp the characteristics of bearing faults and effective diagnostic methods, greatly improving equipment maintenance efficiency. In addition, it can simulate fault situations under different working conditions, enabling users to proficiently grasp the operating characteristics of machinery in various environments, further improving the accuracy of fault prediction.

Application prospects after delivery

After the delivery of these two devices, they will be immediately put into teaching and research work at Ningbo University. In terms of teaching, students majoring in related fields will have the opportunity to learn and practice the knowledge and skills of rolling bearing maintenance and mechanical and electrical equipment fault diagnosis in a real experimental environment, enhancing their professional competence and practical ability. In the field of scientific research, the school's research team will rely on these two devices to carry out a series of cutting-edge research projects, such as developing more accurate equipment fault prediction models, exploring new equipment maintenance strategies, etc. It is expected to achieve innovative scientific research results in related fields, providing theoretical support and technical solutions for the development of the industry.

The successful delivery of the BTS200 rolling bearing full life cycle prediction and maintenance system and the PT700 electromechanical equipment health assessment and fault diagnosis comprehensive test bench is an important step for Ningbo University to enhance its research and teaching capabilities. In the future, schools will fully leverage the advantages of these devices, cultivate more outstanding talents, produce more high-level scientific research achievements, and make greater contributions to the development of society.
