Single-Course English 5 ECTS

Machine elements – basics

Overall Course Objectives

The aim of this course is to give the students :
– An overview of the most basic machine components.
– The fundamental insight making them able to dimension and select appropriate machine components for a mechanical design based on requirements to the component.
– A basic understanding of the working principles of the components.
– An overview of the methods for analysis and design of selected machine components.
– An understanding of the failure mechanisms for the machine components.

Learning Objectives

  • Describe capabilities and characteristics for a number of basic machine elements.
  • Elaborate on the working conditions and other operating conditions for components in a mechanical product.
  • Identify components which are critically loaded.
  • Describe and utilize the models and analysis methods, which forms the base for selecting basic components.
  • Utilize mechanics and strength of materials when dimensioning machine elements.
  • State requirements to materials and functional surfaces for components in a mechanical product.
  • Use the standards, which describes the frame for dimensioning of machine elements, including DS-, DIN-, EN-, and ISO-Standards.
  • Specify tolerance requirements to machine elements and mechanical systems.
  • Read and understand literature in the machine element field.
