Applied Mechanics of Building and Transport Machines (FSI-QAM)

Academic year 2024/2025
Supervisor: Ing. Lukáš Zeizinger, Ph.D.  
Supervising institute: ÚADI all courses guaranted by this institute
Teaching language: Czech
Course type: departmental course
Aims of the course unit:

The aim of the course is to develop the existing knowledge of mechanics and apply it to the problems of building and transport machines. These problems are solved in the area of vibration, including computer support.
The course is intended to extend student’s knowledge of technical mechanics. It is applied to real examples of the machines from the selected branch of study. Main objective is for students to acquire ability to identify the force effects in the mechanisms - when they are starting and braking, as well as ability to analyse and optimise vibrating effects in machines when using common calculating methods.
