- Course objectives supported by learning outcomes
- Students acquaint with function and construction of propulsion and energy transmission systems of machines with combustion and electric motors, hydrodynamic aggregate, open and closed hydrostatic circuit and pneumatic drives. To obtain so knowledge and acquirements necessary for practical decision making with choice drive machines system and for functional design of these systems, leading to choice functionally and energic optimum component of catalogue specialized producers.
- Learning outcomes
- The student is able to make a comprehensive assessment of the machinery drive.
- Syllabus
- 1. Classification of mechanisms according to the type of energy carrier, the transmitted form of energy and the movement of the energy carrier 2. Drive as a subsystem of the machine, energy model of the machine drive, external characteristics of working mechanisms, course of loading of the machine mechanism depending on time 3. Fundamentals of machine dynamics, mass geometry, mass, moments of inertia, oscillations and vibration prevention 4. Electric drives and their control - AC control drives, DC control drives; characteristics and dimensioning of electric drives, heating and load 5. Internal combustion engines and their control; characteristics of internal combustion engines - power, torque, specific fuel consumption; regulation and increase of performance, service life and maintenance, impact on the environment 6. Cardan gears, manual and automatic gears, differentials 7. Hydraulic drives; basic hydraulic circuits open and closed for rectilinear and rotary output movements; hydrostatic transmissions 8. Basic elements of hydraulic mechanisms - hydrogenerators, hydraulic motors; distribution, properties, characteristics, parameters, use, calculation 9.
