MF2010 Component Design 6.0 credits

Komponentkonstruktion

The course Components Design aims at improving the understanding for how components in mechanical products are designed. A number of components are analyzed in the course with regard to function, reliability, forces, stresses, causes of failure etc. The components are partly analyzed by means of known design tools such as Finite Elements and Monte Carlo simulation, but the students are also practiced in making and evaluating models and algorithms of their own.

Learning outcomes

The main goal is to give the students a deeper insight about the ways of thinking that form the basis of components design. Furthermore the course aims at improving the students’ ability to use existing, but also to create new, models that can be used to describe the performance of a component.

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.

Course main content

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;

• estimation of the degree of efficiency in a 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.

The course includes:

• two laboratory works;

• three group assignments;

• two individual assignments;

• an optional oral examination.

Disposition

The project is a collaborative industrial development projects with an optional exam.
The course is mandatory for track Machine Design in the Master program Industrial Product Development.
