The module aims to provide the student with an insight into the analysis of machines / systems through the application of experimental modal testing and basic analysis. In a laboratory-based session with a strong emphasis on practical aspects and associated underlying science and technique, students will participate in the experimental analysis of a precision machine or system. The session will cover the physical principles, practical techniques, data gathering and simple validation/processing together with guidance on results presentation.
