Course Objectives
To provide the students especially for the ones working on structural dynamics, mechanical vibrations and modal testing areas by providing unique inside on the general understanding of experimental techniques in vibration measurements comprising vibration test planning, selection and use of exciters, transducers and sensors, data collection, processing and assessment, in particular with hands on environment for modal analysis and testing.
Course Content
Modal analysis theory, Vibration measurement and testing. Test planning and structure presentation. Vibration exciters, transducers, sensors and analysers. Modal analysis methods including time and frequency domain methods. Structural modification. Finite element analysis and model updating. Structural health monitoring and damage identification.
Course Learning Outcomes
As this course mainly focuses on investigating structural vibrations by putting particular emphasize on the real application of experimental techniques in vibration measurements by maintaining good balance between theory and practical training, by the end of the semester the students are expected to;
- gain a physical feel for the relationships between mathematical models and actual dynamic system behaviour,
- have a firm understanding of the principals of measuring devices and their peripheral equipment,
- develop knowledge of test planning, structure preparation, transducers, actuators, sensors and associated instrumentation for dynamic system measurement and an ability to use different techniques, skills and modern necessary engineering tools for experimental analysis of vibrating structures,
- have enhanced capabilities for digital data acquisition, data reduction and signal processing.
In addition to these objectives, students’ ability of identifying and solving structural vibration problems by designing and conducting tests as well as analysing and interpreting data are assessed by giving the students an opportunity of working on real-life problems either individually or in a group. As a result of this effort, students are expected to acquire the hands-on experience needed to perform modal analysis and testing from start to finish.
