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.

Syllabus

1. Mechanisms classification by kind of bearer energy , carried forms energy and movement bear erenergy 2. Propulsion as machinery subsystem, energic model drive machine, outer characteristics working mechanisms, process loading mechanism machinery in dependencies on time 3. Principles of dynamic machines , geometry matters, materiality, moment ofinertia, oscillating and prevention vibrations 4. Electric propulsions and their proceedings – alternately control propulsions, equablec ontrol drive; characteristics and dimension of electric propulsions, warming and service factor 5. Combustion motors and their proceedings; characteristics combustion motors – achievement, turning moment, specific fuel consumption; regulation and escalation achievement, lifetime and servicing, environmental impact 6.
