1. General information
The aim of this subject is that students of the Degree in Mechanical Engineering, regardless of their specialty, acquire the basic fundamentals of static calculation of machine elements, applying them to the analysis of the simplest elements, such as the calculation of cylinders (thin-walled or thick-walled), as well as the study of the various forms of union between various mechanical elements. The knowledge acquired in this subject is expanded and complemented in the subjects that make up the Intensification of Machines and Vehicles.
These approaches and objectives are aligned with some of the Sustainable Development Goals, SDGs, of the Agenda 2030 (https://www.un.org/sustainabledevelopment/es/) and certain specific targets:
Goal 8, Target 8.2
Goal 9, Target 9.5
Goal 12, Target 12.2
2. Learning results
- Understand the mechanical design constraints.
- Be able to consider different types of variables in the design.
- Know the various elements of machines and understand how they work.
- Be capable of dealing with the basic analysis of machine elements.
3. Syllabus
Agenda:
- Introduction to mechanical design.
- Calculation of machine drives.
- Materials in machines and their properties.
- Stress analysis of machine components.
- Static resistance design.
- Stiffness and deformation.
- Stresses and deformations in cylinders.
- Press fittings.
- Bolted joints.
- Welded joints.
Practical sessions:
P1.- Drive calculation.
P2.- Calculation of actions and dimensioning of simple elements.
P3.- Design of elements applying strength and stiffness criteria.
P4.- Element analysis using SolidWorks Simulation. Design improvements.
4. Academic activities
The teaching process is divided into: theory and problem classes, seminars, laboratory and work. The learning will be based on the understanding of theoretical and practical concepts and their subsequent application in problemsolving.
Attendance to all learning activities is of special relevance to acquire the competencies of the subject.
Theory classes and problems (45h)
Laboratory Practices (12h)
Seminar (3h)
Supervised practical work.
Other activities: Tutoring.
5. Assessment system
The student will have a global assessment test of the subject (10 points) that will consist of:
1. A written exam, with a reasoned short answer, which will include theoretical and practical questions (2 points).
2. A problem exam (8 points), divided into two parts:
• Part I: 2 problems (6pts), on the practical aspects of the subject.
• Part II: 1 problem (2 points), on the aspects covered in the Continuous Assessment activities described below.
Continuous assessment activities:
1. Problem solving (1.5 points). The student will be presented with a problem with several sections that must be solved applying the knowledge acquired sofar.
2. Practical sessions (0.5 hours): Attendance at the practices is not considered mandatory. Students attending the practical session will have the opportunity to answer a questionnaire on the work developed during the session. Those students who answer all the questionnaires may obtain up to 0.5 points once the questionnaires have been evaluated.
The grade obtained by the student will be the maximum of the following two grades:
• The sum of the grade obtained in the Global Assessment test: Practical Theoretical Questions + Part I of problems + Part II of problems
• The sum of the following ratings: Theoretical and practical questions + Part I of problems + (0,5*Continuous Assessment, +0,5*Part II of problems)
In order to pass the subject, this final grade must be equal to or higher than 5.
