Technical Diagnostics II
FSI-XT2Acad. year: 2019/2020
The subject is focused on the most sophisticated knowledge in technical diagnostics of machines and instrumentation. It builds on the facts mentioned earlier in those subjects who are focused on the diagnostics and this subject develops them. Attention is mainly devoted on the problems of vibrodiagnostics, noise diagnostics, radiography diagnostics, tribodiagnostics, electrical diagnostics and remote machine diagnostics. The meaning and the application of multi-parametric diagnostics are shown. By completing this course and subject Technical Diagnostics I, eventually the subject of Basics of Technical Diagnostics, students will acquire comprehensive knowledge of technical diagnostics of machines and equipment. The findings are also based on the content of the Industry 4.0 initiative and Maintenance 4.0.
Learning outcomes of the course unit
A student acquires comprehensive and complex knowledge of the diagnostics of technical systems which can apply in industrial mechanical/electrical engineering practice to solve different problems related to the aforementioned topics.
Knowledge of mathematics and physics at a level of university study. Also, the knowledge of the aforementioned special field in a scope of the previous bachelor study as well as Technical Diagnostics I subject is expected.

Planned learning activities and teaching methods
The subject consists of lectures and tutorials. The lectures are focused on the basic principles and the theory. Attention is also concentrated on the application of knowledge which the students have gained in the subject of „Technical Diagnostics I“. The tutorials are both focused on the practice of the lectured theme and based on the specific and real examples.
Laboratory exercises are realized exclusively using machines and equipment existing in industrial practice. The same applies to the use of diagnostic tools, methodologies and evaluation software. Therefore, the student will be acquainted with the specific activities of industrial diagnostics, possibly also maintenance technicians. Depending upon the possibilities, the lectures of the specialists from industrial practice as well as the excursions in the companies, whose activities relate to the subject, are also organized.
Assesment methods and criteria linked to learning outcomes
The subject consists of exercises and tutorials. Exercises are required. The tutorial is completed with the credit (granted in the 13th teaching weekend). To gain the credit, 100% attendance, student’s activity in tutorials and the protocols processed from all laboratory exercises and approved by the teacher are required. The examination consists from a written test, and the student‘s maximum scoring rate can be up to 100. The evaluation of test results is given by the classification scale according to ECTS.
Language of instruction
The objective of the subject is to acquire the theoretical and practical knowledge of the diagnostics of technical systems. The subject continues in Technical Diagnostics I.
Specification of controlled education, way of implementation and compensation for absences
The student attendance is checked in tutorials (presence and activity). The 100% participation in tutorials is required, and in case of absence, the student will be obliged to compensate, the alternative attendance will be specified by the lecturer.
