The Dynamics and Vibration Research Line, with its 48 faculty members and more than 100 PhD students and postdocs, is the largest one in the Department of Mechanical Engineering. Research activities focus on the theoretical and experimental study of the dynamics of complex mechanical systems. The division’s nine research lines cover a number of areas, ranging from railway engineering to mechatronics, from automotive to wind engineering, and from mobility to the diagnostics of machines and transport infrastructures. Combining mathematical modelling and numerical simulation with in-lab and on-site testing, also taking advantage of the opportunities offered by digital technologies and modern data science algorithms, is how researchers here face research challenges. In addition to promoting an interdisciplinary approach to research, also based on collaboration with other groups inside and outside the Department and with international strategic partners. The Research Line has always had a strong commitment to collaboration with the industrial world. The strength of the Department relies on its people, with their passion and their skills, and its laboratories, unique at national and international level.
