When you have finished the course you will:

1. Knowledge and understanding

• Understand design, function and basic mechanisms of advanced machine components such as clutches planetary and worm gears, rolling bearings and journal bearings.
• Understand design, function and basic mechanisms of systems of machine components such as transmissions and hydraulics.
• Understand how machine components interact in systems
• Know about ongoing research and development activities in the field of machine elements

2. Skills and abilities

• Be able to use modern mathematical models and tools for the analysis, prediction and dimensioning of machine components.
• Be able to select machine components from an energy, environment, service life and cost perspective.
• Be able to dimensioning, analyze and predict the function of systems of machine elements
• Have the ability to select the most suitable components for a system by taking into account its impact on humans, environment, energy usage and climate.

3. Assessment and reasoning

• Been training yourself in engineering reasoning
• Have the ability to simplify and make assumptions when setting up models of machine components
• Know the need for new knowledge in the field of machine elements and understand the future challenges in the field

This is an advanced course on the subject of machine elements. This course picks up where basic courses on machine components ended. This means that we in this course take up more advanced aspects of the most common machine elements. Machine elements such as different transmissions (planetary gears, worm gears, hydrostatic , etc.) , motors ( combustion , hydraulic and electric motors) , bearings ( rolling and sliding bearings ) are treated from a perspective which include strength, energy efficiency, cost, environmental impact and service life.
The system perspective is also addressed in the course. This means that the system of machine elements rather than individual components is treated.
 
The fundamental aim of the course is to give students sufficient knowledge of machine elements and machine element systems so that s/he himself can dimension and select components. Calculations that aims to make the dimension and selection is therefore key. Students will use different software such as multi-physics tools and tools for solving time dependent differential equations.
Research and development in the field of machine elements at companies and universities, are also highlighted .

Lectures, tutorials, home assignments and students’ oral presentations of home assignments.

Home assignments (written report), oral presentation of home assignments, and individual oral examination.
