Industrial Product Design and Development

The aim of this course is to introduce students to the finite element method as applied to one-, two- and three-dimensional problems in engineering and applied science. This presentation is made within the framework of linear elasticity and small perturbations in statics. Starting with prerequisites in mathematics and solid mechanics, the principle of discretization is first addressed through the approaches of Ritz and Gallerkine for one-dimensional media. Next, the problem of numerical integration is approached using the Gauss method. Meshing and validation of computational models is then addressed in the study of surface modeling with 2D elements. Finally, these notions will be used to set up the complete formalism of the finite element method within the framework of bar and beam elements, then triangle-type elements. A practical application of these important theoretical notions is carried out on an industrial calculation code (ANSYS) during practical work and a project.

This teaching unit introduces students to :

- management within the company, presenting the company as an economic and legal entity on the one hand, and the strategic approach in its entirety on the other.

- marketing in business, from market research to operational marketing. The marketing approach will be directly applied to the industrial creation project carried out by the student teams.

Class sessions will be supplemented by a company visit, as well as by a methodological approach based on concretecase studies.

This 42-hour course is divided into two parts (1/3, 2/3) to give the basics of heat transfer and fluid mechanics (3D). Fluids will be considered as continuous media. A particle is an element of volume infinitesimally small for mathematical description, but large enough relative to molecules to be described by continuous functions. This course extends the L3 course on modeling elastic media, as well as the 1D fluid mechanics course.

This 42-hour course is divided into two identical parts running in parallel. The first part deals with the study of vibration problems in discrete media and in 1D continuous media (rope, beams). The second involves the use of variational formulations to reformulate the problems studied in L3 in RDM and 3D elasticity. This enables us to propose optimized approximate solutions. This part of the course provides a link between RDM, 3D elasticity and the second-semester finite element course.

At the start of this teaching unit, the group of students (4 maximum) has a set of documents among which we systematically find the Product Functional Specifications containing a validated solution in principle. The group of students must then propose a critical analysis of the documents submitted and build an organizational plan to produce a technical file containing all the plans for the parts of the product.

In this progression, the student must go through an essential step which consists of defining the product (CAD model) and arguing, through a set of calculation notes, the choice of components retained and the sizing of the product parts.

During the final project review, in the presence of the client, the group of students will present these results.

This teaching unit is the continuation of the "Definition of industrial products" course. Starting from the product definition file, the group of students (4 maximum) must create the functional prototype of the solution that will be validated later. When making the prototype, the group of students must:

manage the subcontracting of parts to be made and the purchase of standard components;

inspect manufactured parts and purchased components;

Assemble the prototype from an assembly graph established by the students.

Based on the characterization of the functions accessible in the CDCF, the group of students must qualify the functional prototype by implementing all the experimental means to verify each of the criteria and by proposing corrective solutions in case of non-compliance.

This course enables students to apply the key stages of a mechanical design approach, from initial specifications to prototype qualification, to one or more concrete cases dealt with in previous years' industrial projects. It thus supports the year's industrial projects by mobilizing the same skills, but on one or more solved cases, unlike the current projects. It therefore requires the mobilization of various skills acquired in other courses, particularly non-technological ones, in the Master's or Bachelor's program (fundamental principle of dynamics, strength of materials, continuum mechanics, vibrations, finite element simulation) on one or more real mechanisms that students can manipulate and experiment with.

The internship is carried out in a company or laboratory. During the internship, students must demonstrate :

understanding of a wide range of basic sciences and the associated ability to analyze and synthesize;

its ability to mobilize the resources of a specific scientific and technical field;

its ability to design, implement, test and validate innovative solutions, methods, products, systems and services

its ability to carry out fundamental or applied research, to set up experimental systems, and to be open to the practice of collaborative work;

its ability to find, evaluate and exploit relevant information;

its ability to take account of the company's challenges: economic dimension, respect for quality, competitiveness and productivity, commercial requirements, business intelligence ;

its ability to take into account workplace relations, ethics, responsibility, safety and health issues;

its ability to fit into professional life, to integrate into an organization, to lead it and to help it evolve: exercising responsibility, team spirit, project management, communication with specialists and non-specialists alike;

ability to work in an international context: mastery of one or more foreign languages and cultural awareness;

the ability to know oneself, to self-assess, to manage one's skills (particularly in the context of lifelong learning), and to make professional choices.

This course is an introduction to the new design methods associated with additive manufacturing techniques, enabling you to produce a part on a 3D (polymer) printer, from its design on the computer (CAD) in relation to the capabilities of the process, the optimization of its geometry (topological optimization), the preparation and launch of manufacturing, and the finishing stages after printing (completion).

Although natural composite materials have been used for thousands of years, the high technology of advanced composites has only been used in the aerospace industry for fifty years. Applications are increasingly varied: from aircraft structures and hydrogen tanks to tennis rackets and boats. The aim of this course is to analyze and design laminated composite structures using industrial calculation codes. To achieve this, the different components of petrochemical and natural composites are presented. Next, the implementation processes are discussed. Finally, a theoretical and applied study of laminated composites is carried out. A practical application of these important theoretical notions is carried out on an industrial calculation code (ANSYS) during practical work and a project.

The objective of this module is to practice numerical simulation tools (finite element software or mechanism simulation) by insisting on their limitations, through case studies on: HPP isotropic elasticity, modal analysis, mechanism simulation, topological optimization, thermal and thermomechanical analyses,...). In most of the examples covered, we will try to show the interest of experimentation, both to feed the models upstream and to validate them at the output.

The objective of this UE is to develop a new product. The idea or new need is initiated by the project group of 2 or 3 students maximum. This innovative project covers the different phases of a project from the statement of the need to the realization of the functional prototype (see the pre-industrialization of the product) through the analysis of the competition, the search for a solution in principle, the definition of validated solutions as well as the writing of the claim of their patent when the technical solution is defined. This innovative project is associated with 5 other teaching units:

CAD and prototyping, which corresponds to the implementation of the digital mock-up and the creation of the functional prototype;

graphic design in which the student develops the communication elements for this innovative project: packaging, poster, presentation video, first page of the website;

eco-design in which the student defines the "environmental value of his innovative product".
