Applied Mechanics of Building and Transport Machines
FSI-QAMAcad. year: 2018/2019
The course deals with the following topics: The fundamental solution methods of dynamic systems of branch machines, vibrating systems of branch machines including matrix solution methods. Computer support of the dynamic systems solution - DYNAST. Approximate solution methods of dynamic systems. Dynamics of continuous systems - vibration of prismatic bars. MKP application in dynamics. Dynamics of vibrating transport and compacting.
Learning outcomes of the course unit
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.
Successful completion of the course is conditional on the basic knowledge of technical mechanics, physics and higher mathematics.

Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Part of the course can be excursions to the companies, which manufacture or operate the equipments from the thematic area of education.
Assesment methods and criteria linked to learning outcomes
The examination consists of a written and an oral part. Written part of examination is evaluated by 50 points and it is necessary to get at least 20 points to continue in the oral part. Oral examination is marked independently and it is the same weight at the written part.
Language of instruction
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.
Specification of controlled education, way of implementation and compensation for absences
Course-unit credit is awarded on condition of having attended the exercises actively and worked out assigned projects. Presence in the exercises is obligatory.
