MS Student Myeongbaek Youn from Prof. Byeng Dong Youn’s Lab Receives Best Student Paper Award from Korean Society of Mechanical
MS student Myeongbaek Youn from SNU Dept. of Mechanical and Aerospace Engineering System Health and Risk Management Lab (Advisor: Prof. Byeng Dong Youn) received Best Student Paper Award from the Korean Society of Mechanical Engineers 2018 Annual Conference for his research titled “Vibration-Based Fault Diagnostics of Planetary Gears Under Non-stationary Conditions.”
The title is “Performance Evaluation of Planetary Gearbox Fault Detection Algorithm at Variable Speed Conditions based on Time-Frequency Analysis.” The research performed a comparative analysis of fault diagnosis of planetary gears under variable conditions where speed changes with time, using Short-time Fourier Transform, wavelet transform and Wigno-Ville distribution, and examined the characteristics of various time-frequency analyses.
