On the afternoon of January 10th, Professor Luis Baeza from the School of Mechanical and Materials Engineering at the Polytechnic University of Valencia in Spain gave an online academic lecture titled Influence of wheel rotation on instrumental wheelset measurement in Conference Room 8A613 of the Modern Transportation Engineering Center. The lecture is hosted by School of Urban Railway Transportation at Shanghai University of Engineering and Technology, and presided over by Teacher Zhong Shuoqiao.
Professor Luis Baeza introduced the application of force measuring wheelsets in rail transit and pointed out that there is currently no clear explanation of the structure of force measuring wheelsets and the accuracy verification of their measurement results in major standards. His research found that the measurement results of wheel rail forces in static and dynamic behavior of force measuring wheelset systems with different structures are different, and the difference in wheel rail force measurement results between the two states becomes more significant with the increase of vehicle operating speed. Professor Luis Baeza, based on the dynamic model of wheelset rotation inertia effect and structural flexibility, introduced how the dynamic behavior of wheelsets affects the measurement accuracy of force measuring wheelsets, and proposed the challenges faced in the design of force measuring wheelsets.
After the meeting, Professor Sheng Xiaozhen and Professor Luis Baeza of the college had in-depth discussions and exchanges on relevant issues, greatly expanding the students' horizons. Professor Sheng recommended many more specific research directions to the students, encouraging them to work hard in scientific research and achieve results.
