Course contents:
In the first part of the course, important topics with regard to safe calculation and dimensioning of machine parts are emphasised. Key elements are as follows: Stresses due to static and dynamic loadings. Deformation of machine parts, design to avoid stress concentrations, metal fits and tolerances, power transmission, shafts and critical speed, coupling design, welding, screws fasteners design, breaks, springs, gears, bearings, belt/chain drives. Later in the course, machine parts and mechanisms are put into a larger perspective with regard to the development of mechanical and hydraulic power systems, such as transmissions and larger hydraulic systems. Key elements are as follows: Hydraulic valves, pumps, motors, pistons, electrical control units, mechanical and hydro-mechanical transmissions. In addition, an introduction to the use of standardised component symbols for planning mechanical and hydraulic systems is given, with practical examples from tractors, cranes, mass transfer machines, transport machinery and industrial installations etc. The course contains compulsory exercises, calculation exercises and planning exercises. The exercises focus on understanding, measuring and describing characteristics of single elements and the construction of complex installations and systems.
Learning outcome:

Through the course, students will learn how to apply elementary force calculations for machine parts and develop skills in the dimensioning of machine parts, power systems and machines. Also, they are to amass knowledge of the most used machine parts, their function and key mechanical and hydraulic systems. The students are to understand how external forces affect construction parts and what precautionary rules should be taken when dimensioning. Also, they are to understand and use the parameters, formulae, standards and criteria required for manual calculations and dimensioning with the needed security against deformation and fatigue. The students are to understand static and dynamic energy as well as force transfer through incompressible liquids and be able to calculate energy losses, efficiencies and outputs of mechanical, hydraulic and combined systems and transmissions. The students are to become familiar with standard symbols for transmission- and hydraulic elements and be able to use them in the design of simple and more complex mechanical and hydraulic systems. When the course has been completed, the students are to be able to calculate, dimension and specify machine parts, mechanical- and hydraulic systems key elements for modern machines that are used in agriculture, forestry, the building and construction sector as well as in industry and transportation. Energy efficient systems and solutions are emphasised in the course.

Learning activities:
The course is given as a combination of lectures with a theoretical foundation and examples. During the course, calculation exercises are given where the students get to try out and practice their theoretical knowledge. Calculation assignments and exercises and system-planning assignments are compulsory and feedback on achievement is given along the way. The laboratory exercises are conducted in small groups of 3-4 students, and include the function and characteristics of machine parts, mechanisms and hydraulic systems (e.g. water and oil hydraulics), measuring forces, torque and power and the use of practical control engineering.
Teaching support:
The subject teachers are available for support in connection with calculation exercises in working hours, and by e-mail and phone outside of the teaching time. Laboratory exercises are carried out under the guidance and technical assistance from other persons at the department that are easily available during the working day. In the period leading up to the examination, extraordinary assemblies/revision lectures will take place. By arrangement, there can also be exercise practice outside of the normal work hours.

The course is compulsory for MPP (Machinery-, process and product development)students and IE-students (Industrial Economics) combining graduate level courses in Machinery and Product development and Business development/management. An equivalent course is also given at certain state-owned colleges, in the engineering education and can be credited by admitting students to higher year groups.
The external and internal examiner jointly prepare the exam questions and the correction manual. The external examiner reviews the internal examiner's examination results by correcting a random sample of candidate¿s exams as a calibration according to the Department's guidelines for examination markings.
Allowed examination aids: Calculator handed out, other aids as specified
Examination details: One written exam: A - E / Ikke bestått
