MDI course description!

What this course is about...!

Head line: MDI - Machine Dimensioning!

Course Type:

Obligatory course for the Mechanical Engineering study and Export Engineering

study, mechanical line.Credits points: 10

Prerequisites:

Static, science of materials and basic drawing techniques.

Evaluation & Examination:

Oral examination (approx. 15 minutes) based on an exam case prepared in advance.(approx. 20 minutes for preparation).

Course main purpose:

The main purpose of this course is for students to acquire the competences needed

to design and dimension a simple machine assembly.

Students will in some issues test theory in practice through laboratory

work/assignment to gain a deeper understanding of science issues.

Course secondary purpose:

Having completed this course, students should be able to:

o Explain the theory behind the calculation basis for machine assemblies.

o Explain construction and control principles.

o Prioritize the choice and conduct of relevant analysis for the design and dimensioning ofsimple machine assemblies.

o Interpret and use the catalogue data for main components.

o Set up specific demands and criteria for an assembly based on an arranged set of

demands and criteria for a sample machine construction.

o Set up and analyze possible solutions for the design of assemblies based on specific

demands and criteria.

5/16



Main topics:

The physics basis for machine assemblies formed of main components such as

motors and actuators which are electrically or hydraulically driven, the choice of

mechanical components such as gears, clutches, brakes etc.

Expected workload:

9 weeks of 13 lessons per week.

Expected minimum workload for students is 270 hours.

Teaching will balance theory with small exercises.

Ooh, Im so excited!

Bring it on- Im ready!

I know that!

I didn't know that!

Thats too hard!

I dont believe it!

Fuck teacher!

Im bored!

I need to learn it!

Ah, thats interesting!

Is that how it is!

Im learning!

I KNOW IT!

Learning processThings to notice!

Course presentations will notbe given before a lesson!

Presentations will be available shortly after as pdf-file in our study-room.

If you are not participating, you will miss this learning for good!

But... If you have an acceptable reason, the teacher may help you get updated.

Always speak up loud and clear, so all can hear you!

...Especially because the teacher is getting old and hear very badly...

Learning processThe challenges!

Participatein discussions!

Askwhen you are in doubt!

Let your fellow students talk... You may learn something!

Acceptthat all can make mistakes! (including the teacher! - theoretically)

Be helpful, you may need it yourself some day!
