Learning unit contents

This course intoduces to the design of the most usual machine elements. It has also an introduction to metal cuting fabrication processes.

CONTENTS
Intoduction to ISO tolerances. Force determination in a transmission.
Preliminary design of a shaft. Fatigue resistance and criteria. Design of shafts Shaft-hub assembling. Rolling bearing computation. Journal bearings. Gears : spur and helical meshes. AGMA and ISO methods Belts and puleys.
Machining technologies: turning and milling operations.

Learning outcomes of the learning unit

After this course, the student will be able to dimension the most used machine elements.

- Determination of loads
- Determination of reduced forces (M, N, T etc...)
- Determination of permissible stresses
- Sizing of shafts, long and short
- Fatigue calculation
- Shaft dynamics elements
- Determination of catalog elements

This ability will be useful in the integrated project.

This course contributes to the learning outcomes I.2, III.1, III.2, IV.1, IV.2, V.2, VII.2 of the BSc in engineering.

Prerequisite knowledge and skills

Prerequisites: Geometry, rational mechanics, elements of strength of materials.

Planned learning activities and teaching methods

Oral course and exercises which are applications and solution of a desgin project.

Mode of delivery (face to face, distance learning, hybrid learning)

face-to-face course.

Written work / report

Continuous assessment


Additional information:

Part 1: Continuous evaluation

• The students have to solve several homeworks (mini projects) by groups of two. The assessement is based on the reports.
• Lab reports of the machine tooling tranings

• Exam includes a part with questions of theory and a part of problem solving ( no books; only a short formular allowed - to be determined precisely during the course)

• If applicable, attendance to the lab sessions is mandatory to get the credits
• Attendance of 60% to the supervised work sessions is mandatory to get the credits.
• To get the credits, it is necessary to obtain marks greater or equal to 7/20 in both parts. In case of failure in one of the two parts, the final mark is the lowest mark of the two parts.
