Mehran Sadri received his PhD in vibroacoustics from Iran University of Science and Technology (IUST), in 2016. As part of his PhD program, he joined the Section of Acoustic Technology at the Technical University of Denmark (DTU) in 2014. For his PhD thesis, he developed a Hybrid FE-SEA model for the noise and vibration analysis of a passenger coach, and proposed a Bayesian inversion approach for updating the model. Mehran Sadri has been a member of Iran’s National Elites Foundation. He is currently working as a postdoc researcher in the Section of Railway Engineering at Delft University of Technology, and his main focus is on the track dynamics, and long-term performance analysis of railway tracks.
Mehran is specialized in vibroacoustic analysis of mechanical structures.His general research expertise and interests are,- Noise and vibration analysis- Structural acoustics- Structural dynamics- Model updating & inverse methods- Noise and vibration measurements- Railway dynamics
Both environmental vibration radiation from train operation and long-term track degradation are governed by the ‘flow’ of mechanical energy through the railway super- and substructure. This flow consists of three elements: (1) input, provided by the rolling stock moving along and interacting with the structure; (2) throughput, with a transmitted and an absorbed part, the latter governing local degradation; (3) output in the form of vibration radiation.
Mehran will be working on characterization and control of this energy flow, which is vital for limiting vibration hindrance and track maintenance.
