Prerequisites
This course is taught in the first year of the master MECA and ELME mechatronics. It assumes that students already have basic skills in technical drawing. The aim of the course is to introduce the elementary knowledge necessary for the mechanical design of the elements that compose a machine. It is thus the basic course before a specialization 'design and manufacturing' and will contribute to prepare students to a future job as R&D engineer in the technical department of a company.
Main themes
Functional analysis of machines and their components
Properties of component
Elements of calculus of machine components.
Learning outcomes

At the end of this learning unit, the student is able to :

1 Specific learning outcomes of the course
·         Write  functional specifications for a machine
·         Identify the functionalities of a machine (actuation, bearing systems, transmission, sealing, ')
·         Estimate the installed and maximum power, the energetic consumption and the efficiency of a machine
·         Design a simple machine following an adapted methodology
·         Identify the basic hypotheses of elements dimensioning
·         Dimensioning  following  various  criteria  (yield  strength,  elastic  compliance,  fatigue)  of  usual elements (e.g. shafts)
·         Dimensioning while taking into account the effect of dynamic loading, stress concentration and residual stresses
·         Choose machine components (bearing, gasket, transmission) Read and interpret the drawing of an existing machine
·         Hand drawing of machine components and overall drawings
·         Placing tolerances for a mechanical system
·         Machine component design : threaded fastener and power screws, rivet and welding rolling bearing, sliding bearings,  clutches and brakes, power transmssion components (gears, belt, chains,  etc..), shaft and assocated part (key, pin, coupling, ')
In consideration of the reference table AA of the program " Master's degree civil engineer mechanics ", this course contributes to the development, to the acquisition and to the evaluation of the following experiences of learning:
AA1.1, AA1.2
AA2.1, AA2.2, AA2.3, AA2.4, AA2.5, AA2.6, AA2.7, AA2.8
AA4.3, AA4.4
AA5.1
 
Content
At the end of the course the students will be able to :
  1. Describe the functionalities of a machine (actuation, bearing systems, transmission, sealing, …). Write  functional specifications for a machine and conduct a risk analysis.
  1. Design a simple machine following an adapted methodology. Take into account of digital manufacturing technologies, environmental, social, and economic impacts from the initial phase of design through to the end of life (sustainable design)
  1. Use the propose  vocabulary for the various machine items.
  1. Identify the basic hypothesis of elements dimensioning. Estimate the installed and maximum power, the energetic consumption and the efficiency of a machine.
  1. Dimensioning following various criteria (static strength, elastic deformation, fatigue, …) of usual elements (e.g. shafts)
  1. Choose machine components (bearing, gasket, transmission, brake, clutch, hydraulic, spring)
  1. Read and interpret the drawing of an existing machine. Hand drawing machine elements and overall drawings. Placing tolerances for a mechanical system
Teaching methods
Part of the course is taught as lectures and by problem and project based learning (PBL) within groups of 6 students.  Two projects are proposed:
  • Project 1 : design of a machine
  • Project 2:  Digital manufacturing of the solution
Evaluation methods
Students will be evaluated on the basis of the two projects and a written exercise exam. 
Project 1 and 2 will be assessed on 3 points each  in  the final grade . The note for the two projects are acquired once and for all (there is no second chance in September).
The written examination in session will be worth 14 points in the final grade. Students must score at least 7 out of 14 on the exam to receive credit for the entire course.The written exam will contain exercises, theoretical questions and at least one drawing, the book Juvinall and the bearing catalogue are authorized, the book on technical drawing is not authorized.
