MF2010 Component Design 6.0 credits

The course is based on problem solving. An existing product is used as example throughout the course and most assignments concern analyses and redesign of this product.

Topics treated are:

• failure mechanisms in mechanical components;

• analyses of the forces in a mechanical product;

• dynamic loading; periodic loading; transients.

• fatigue: standard analysis; cumulative fatigue damage theory;

• standard design methods for components, such as gears;

• advanced analysis of a components strength and optimization of its weight;

• modeling of non-standard components;

• the use of bearing design analogies applied for other components.

A student that has completed the course shall:

• have a good ability to use knowledge from basic subjects, such as mathematics, mechanics and solid mechanics, in the design of machine components;

• be able to calculate deformations and stresses in bending of short and thick beams;

• be able to perform fatigue analyses using the theory of cumulative fatigue damages;

• be able to describe common failure mechanisms which are limiting the performance of a product;

• be able to calculate the degree of efficiency of a product;

• be trained in using international standards when designing standard components;

• be able to use and evaluate analytical and numerical methods from solid mechanics when designing components and also be able to judge the validity of the methods;

• be able to create own models that describe the function of non-standard components and use the models to optimize the performance of the component;

• be able to apply knowledge about bearing design on components with similar contact conditions as in a bearing.

If the course is discontinued, students may request to be examined during the following two academic years.

• INL2 - Hand in Task, 2.0 credits, grading scale: P, F
• LAB1 - Laboration, 1.0 credits, grading scale: P, F
• TEN1 - Written examination, 3.0 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

• All members of a group are responsible for the group's work.
• In any assessment, every student shall honestly disclose any help received and sources used.
• In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
