The objective of this teaching unit is to provide students with the tools necessary for technical communication in mechanics, with an emphasis on reading technical drawings, technical drawing (vocabulary, technical drawing rules, projections, intersections, cuts, sections, technological components, etc.) and the creation of virtual models using CAD software (Solidworks).

This ECUE provides knowledge about different manufacturing processes (machining, casting, forging, plastics processing, etc.).

It also enables students to learn the classic rules for drawing mechanical parts in line with the most common methods of obtaining raw materials.

Based on specifications and/or a design drawing, students must be able to: choose a manufacturing or assembly process by producing the drawings associated with the process.

They must also be able to produce a prototype using traditional machining or CNC "rapid prototyping" techniques, and check specifications during and after machining. They will also learn about casting and welding during a practical workshop.

Finally, it helps to make future designers aware of the problems encountered in the engineering department when producing parts from a design drawing.

This module is a basic module on the physical properties of materials and on techniques for dimensioning mechanically simple components or systems.

The properties of materials are examined using tensile testing, binary diagrams, and microstructure analysis.

Component dimensioning involves choosing the most suitable material and defining the geometry to ensure static and fatigue resistance. The dimensional analysis process also makes it possible to determine the characteristics of a more complex system based on experiments conducted on a scale model.

This course unit concerns the study of rigid body mechanics. It is the natural continuation of the course unit devoted to the kinematics and statics of rigid bodies in L1. In this course unit, we will place ourselves in a dynamic framework and apply the Fundamental Principle of Dynamics. Writing this principle requires knowledge of the tensor of external actions, studied in L1, as well as knowledge of the dynamic tensor. The latter can be calculated using the kinetic tensor, which involves the concept of moment of inertia for a rigid solid. The main applications studied in this course concern rigid solids or simple cases of articulated systems of rigid solids. In addition, we will study the special case of contact and friction actions (Coulomb friction) and we will discuss the kinetic energy theorem.

The first semester course reviews the grammar concepts essential for oral and written communication (tenses and aspect, asking questions, comparisons and superlatives, passive voice) as well as essential general vocabulary (numbers, measurements, shapes); It also includes an introduction to technical vocabulary (basic building materials, airplane engines, bike parts, electronic devices) through lessons and videos on topics related to mechanical engineering.

Finally, numerous activities are offered to promote oral expression skills (presentation vocabulary, simulations, role-playing, and tabletop games) so that students are able to describe the specific features, functions, and uses of a technical device of their choice during an oral presentation in groups of two.

Grammar aspects are limited to a review of modal auxiliaries.

The vocabulary is much more focused on the various elements involved in the design and operation of different types of combustion engines and on emerging technologies (drones, driverless vehicles, 3D printing).

Students must also produce a CV in English and practice writing emails in a formal style, so that they are prepared for situations when looking for internships or jobs where English proficiency will either be necessary or an additional skill.

Practicing expression is always the main objective, with an individual oral presentation at the end of the semester on their second-year mechanics project.

The aim of this course is to enable students to acquire or consolidate language skills that will be essential in their professional lives. English is now the international language of communication in the scientific and technical world, both for scientific publications and at conferences and meetings between professionals.

This EU concerns the study of mechanical systems as chains of rigid solids connected to each other by mechanical links.

The study of mechanical systems will be conducted from a kinematic, sthenic, and energetic perspective.

The concepts of torsors, connections, the Fundamental Principle of Statics, geometry of masses, the Fundamental Principle of Dynamics, and energy will be revisited in the study of mechanical systems to determine connection forces and equations of motion.

This module follows on from module HLME303 and introduces the initial analysis tools required to implement a mechanical systems design approach. It aims to provide methods for analyzing and dimensioning mechanical systems built using the most common technological components. 

This module is based solely on lectures and tutorials, but maintains a strong interaction with the HLME401 "Technology Project" module in order to put all the skills acquired into practice in a case study. Initially, the main methods of modeling mechanical systems (functional analysis, kinematic diagram) will be covered. Then, we will focus on the essential technological components used to achieve rotational guidance (plain bearings) or power transmission (belts, gears).

This course unit enables students to acquire skills in computer-aided design and mechanism simulation.

With regard to CAD, the course will cover part mode (3D design of a mechanical part), assembly mode (design of a mechanism), and drafting of parts or assembly drawings.

As part of the simulation, we will use CMAO software to examine the kinematic and dynamic behavior of mechanisms made up of rigid solids.

This project allows students from different initial training backgrounds to apply the theoretical and/or technological concepts they have previously learned and in other modules of the training program, within the framework of studying a proposed mechanical system or one of their choice (after validation).
