Goals and objectives
of the course in terms
of competences and skills
|To acquaint students with the fundamentals of technical fluctuations. In order to achieve this aim the following tasks should be fulfilled: 1st Analyse the fundamental relationships of the discrete and distributed system vibrations. 2nd Teach students how to solve the task on oscillations and vibrations applying the computer programs. 3rd Improve students' knowledge of physics related to the fields of vibrotechnics and vibromachinery 4th Teach students the skills required to be proficient in the calculation of the vibration of the technical and engineering facilities.|
At the end of the course students will be able to evaluate the fluctuation/vibration processes in nature in different forms. - Laboratory work.
At the end of the course students will be able to provide examples on the technical movements and stability. - Questions in the practical work
At the end of the course students will be able to analyze major changes of the mechanisms and machinery. - Questions at the end of the lecture.
At the end of the course students will be able to distinguish between fluctuations/vibrations and the stability of technical and engineering tasks. - Assessment test
At the end of the course students will be able to formulate a mechanical object resonance tasks. - Assessment test
At the end of the course students will be able to assess the impact of fluctuations and stability on the machine dynamics and technological processes. - Exam
