主講人：Abdollah Malekjafarian （愛爾蘭都柏林大學）
Abdollah received the B.E. and M.Sc. degrees in Mechanical Engineering from Semnan University, Iran in 2007 and 2010, respectively. He finished his PhD in Civil Engineering at University College Dublin in 2016. His PhD focuses on drive-by bridge health monitoring using the response measured on a passing vehicle. He is currently an Assistant Professor in the school of Civil Engineering at UCD since June 2019. He is author and co-author of 53 publications including 1 book chapter, 22 peer-reviewed journal articles and 30 conference papers.
Structural Dynamics and Random Vibrations, Operational Modal Analysis for Transport Infrastructure and Offshore Wind Turbines.
He is currently working on two main areas：
(i) Transport infrastructure: He is currently developing a robust and low-cost approach called “indirect” or “drive-by” for monitoring of critical structures in motorway and railway networks. The idea is to use an instrumented vehicle (a truck or train) which travels through the system and monitors roads and highway bridges or rails and railway bridges. This approach shows many advantages compared to direct methods (where the sensors are installed on the structure) in terms of equipment needed, specialist personnel on site, economy, simplicity, efficiency and mobility. He is currently working on the main challenges in this field such as; data science challenges, network connections, signal processing methods etc.
(ii) Offshore wind turbines: A significant challenge to reduce the cost of offshore wind development is the design of efficient and reliable substructures for turbines. He is currently working on numerical modelling of dynamic soil-structure to investigate the soil damping effects for various turbine geometries, seabed conditions, and loading effects in an effort to provide more accurate soil damping values. The objective of this work is to provide more efficient and reliable designs for offshore wind turbines and their substructures which may cause significant cost saving.
