Course detail

Measurement and Experiment

FSI-ZEMAcad. year: 2020/2021

The course introduces to the students the meaning, principles and planning of technical experiment in the work of mechanical engineer. It also describes the basics of modern methods for measuring mechanical quantities and the structure of measuring instrument chain. It deals with the measurement of kinematic quantities, forces, torques, pressures and the analysis of continuous and discrete signals in the time and frequency domain. It defines the basic concepts and categories of reliability and technical diagnostics. Special attention is paid to vibroacoustic diagnostics.

Aims

The aim of the course is to introduce to the students the contemporary methods, instrumentation and computer technology for measuring basic physical quantities. These quantities serve as inputs for mathematical analysis used both for technical diagnostics of machines and for identification of virtual models.

Specification of controlled education, way of implementation and compensation for absences

Presence at lectures is recommended, presence at laboratory exercises is mandatory and checked by the teacher, one absence can be substituted by laboratory exercise with other group in the same week or by elaboration of substituting task. In case of long-term absence, the compensation of the lost lessons is under the competence of the course guarantor – elaboration of special task.

Recommended optional programme components
