The aim of the course is to transfer knowledge on main methodologies, tools and standards functional to the improvement of the quality, reliability and safety of industrial products.

Students will acquire:

CC3: Systematic knowledge and understanding of the key aspects of mechanical design of industrial engineering and its methods. In particular: understanding of which are the most suitable methods in order to define a product and its characteristics; knowledge of the technology of the materials that can be used, of the mechanical study of parts and assemblies, their dimensioning, their static and dynamic behaviour and interactions between components. The technologies for their production and their graphic representation are also areas of knowledge and understanding.

CC8: Knowledge and understanding of the wider multidisciplinary context of engineering with a particular focus on problem solving, which starts from the problem to identify causes and possible measures (typically multidisciplinary) to tackle them.

CC10: Knowledge and understanding of applicable engineering techniques and methods (and their limitations) in non-technical fields

CA3: Applying knowledge and understanding related to the most appropriate methods of analysis, modelling, verification and experimentation to design, analyze and test machines and plants. This includes: the interpretation and drafting of mechanical parts and machines (also using dedicated CAD systems); the sizing and the functional and structural verification of components and mechanical groups subjected to static and fatigue stress; the functional setting of the design of a mechanical system, applying the principles of kinematics and static principles; analysis of the characteristics of metallic and polymeric materials for the production; the choice of the best production process aimed at the creation of mechanical components; analysis and design of production systems including the study of reliability, safety and economic and environmental sustainability.

CA6: Applying knowledge and understanding problems related to identifying, formulating and solving industrial and specifically mechanical engineering problems, defining the specifications, technical, but also social, health and safety, environmental and commercial constraints, and resolving them using established methods, thus leading to engineering projects adapted to the level of knowledge and understanding developed. Projects may concern products, devices, machines, energy systems, automatic systems.

CT2: Coordinated work group
CT4: Graphic representation and communication (drafting of diagrams, graphs and tables)
CT5: Understanding of technical standards

Nothing.

Lectures and tutorials.

Possibility of organizing educational visits to companies operating on the topics covered by the course.

Oral test. The questions are of a theoretical and applicative nature regarding the areas of quality, reliability and safety of mechanical constructions. The student must demonstrate that he has acquired a basic knowledge of the topics, ability to approach problems, and familiarity with the use of methodologies and tools concerning the subjects being taught (CC3, CC8, CC10 competences). The questions during the oral exam are aimed at ascertaining a good level of achievement of the skills reported in the training objectives (CA3, CA6 capacities).

The reliability section concerns: the elements of descriptive statistics and the main statistical distributions and data analysis; the reliability of the systems; reliability measures and analysis and the main design methods adopted in the reliability sector (such as the FMEA, FTA, Hazop, etc.). Also in this case, on the main topics discussed, exercises are carried out to promote the learning of the concepts by the learners.
In the section on safety, there are references to European regulations on the market of products and to the Machinery Directive, with particular focus on the procedure for CE marking which must be followed by a manufacturer for placing the machine on the market, including the documentation which must be prepared to accompany it (e.g. Technical Construction File, Instruction Manual, Declarations of Conformity).
