|University:||Slovak University of Technology in Bratislava|
|Faculty:||Faculty of Mechanical Engineering|
|Course unit code:||210653_IDP|
|Course unit title:||Vibration and Noise of Transport Technology|
|Mode of delivery, planned learning activities and teaching methods:|
|Recommended semester/trimester:||Manufacturing Systems and Quality Management (in english language) - master (compulsory), 4. semester|
|Level of study:||2.|
|Prerequisites for registration:||none|
|During the term the students actively participate on the lectures and experimental seminars, which can be evaluated on the end of semester by maximal 20 points. The result of the experimental seminars are technical reports (TP), where the quality of TR are evaluated. To pass the practice is necessary to obtain at least 11 points.|
Exam, consisting of written and oral part is rated a maximum of 80 points. On successful completion of the exam should be obtained at least 55 points.
Students will get credits for the subject if they successfully complete the written tests and exam. Evaluation is done as follows: A 87-100 points B 79-86 points C 71-78 points 63-70 points D, E 55-62 points.
|Learning outcomes of the course unit:|
|Obtain the knowledge about the methods of primary and secondary reduction of mechanical vibrations and sound waves (vibration) of the transport technology and movable and stationary machines. It based on the latest knowledge, information and theoretical and experimental research in the field of vibro-acoustic diagnostics of mechanical systems and monitoring their conditions, vibro-insulation of driving aggregates mounting and passive and active noise reduction methods. It also includes theoretical knowledge of the vibro-acoustic wave propagation through the body car and the structures of the transport technology and surrounding, the absorption principle vibro-acoustic energy materials and device technology and methods of measurement of dynamic loading of mechanical systems, structures, human and environment. The content follows the requirements of legislative documents of the EU (the Directive) and international and European standards aimed at reducing the dynamic load of the transport technology, machinery, mechanical systems, structures and environment.|
