BIO2100 Histopatologi og cytologi Emneplan

Ingen hjelpemidler ved eksamen

This is a micro course offered to students who want to learn the basics of Digital Twin Technology applied in Condition and Structural Health Monitoring. The course will give an introduction to predictive maintenance of structures and rotor systems supported by digital twin models. The students will get hands on experience with both the hardware and simulation models controlled by an IoT system.

This course will teach how to collect and apply the right data from both physical and virtual models (the digital twin) to lower the maintenance costs while extending the service life of products.  The students will also learn the most important concepts and terms in structural dynamics like eigenfrequencies and eigenmodes. These terms will be explained by two simple but very intuitive demo rigs adding "live action" to the classroom teaching!

These two rigs will provide an experimental-based learning approach. One rig will demonstrate rotor dynamics and what happens when running an unbalanced motor axle at critical speeds. The other rig will demonstrate the interaction between applied loads and inherent eigenfrequencies and mode shapes (resonance problems). The physical rigs will be complemented by simulation models providing additional information about the physical rigs when critical loaded.

Alle besvarelser vurderes av én intern sensor. Ekstern sensor deltar i utarbeidelsen av eksamensoppgaver og vurderingskriterier.

Bestått første og andre studieår.

After completing the course, the student should have the following overall learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

On successful completion of this course the student has knowledge of:
