Educational goal:

Acquisition of in-depth knowledge of experimental testing and analysis of machines.

Educational outcome:

Acquisition of basic knowledge for scientific work in the field of experimental investigation of machines with special attention on methods of stress – strain state determination using strain gauges and investigation of operating states of rotating machinery using vibrodiagnostical methods.

Course content:

Application of strain gauges. Stress - strain relations. Strain gauge principle of operation. Selection of strain gauges. Application of strain gauge on test object. Wheatston bridge. Measurement amplifiers. Software for analysis (HBM Catman). Signal types. Signal representation in time and frequency domains. Fourier transform. System analysis (excitation and response), transfer function, coherence function. Digital signal processing and errors. Vibration of rotating machinery - spectral maps, order tracking, relative phase analysis, orbt analysis, experimental modal analysis. Portable and stationary acquisition systems. Software for data analysis: 01dB-Metravib XPR, 01dB-Metravib dbFA, Vibrant MeScope etc

Teaching methods:

Lectures, self-study research, consultancy. Lectures are conducted in combination. Lectures in theoretical part are followed by examples which serve to clarify the theoretical part of the curriculum. Parts of the course can be taken in several parts (which makes up the entirety) during the semester and also through course projects which are presented orraly.
