| Course code : | ME-DME1-U1 | ||
| ECTS Credits : | 10 | Status : | Compulsory |
| Revised : | 11/04 2012 | Written : | 11/04 2012 |
| Placement : | 3. semester | Hours per week : | 9 |
| Length : | 1 semester | Teaching Language : | English |
| Objective : | The overall course objective is to provide the students with the basics of machine design, including the design process, mechanics and materials, failure prevention under static and variable loading, as well as the characteristics of the principal types of mechanical elements. In addition, the course will give the students a firm foundation to enable them design appropriate machine components for a machine or a structure, based on requirements to the components. A student who has met the objectives of the course will be able to: • Use mechanics and properties of materials in the design of machine elements. • Apply theories of failure to predict failure of machine components subjected to static and variable loading. • Describe strength and characteristics of a number of important machine elements. • Elaborate on the working conditions and other operating conditions for components in a mechanical system. • Identify components which are critically loaded. • State requirements to materials and surfaces for components in machines and structure. • Use the standards, which describe the frame for designing machine elements, including American standards (ASME, ANSI, and SAE), European standards (EN, DS) and International standards (ISO). • Specify tolerance requirements to machine elements and mechanical systems. • Read engineering literature on machine design. • Learn new topics in machine design through guided projects. • Organize project work in small groups. • Write a professional project report containing the engineering analysis and the solutions of the problems posed in the assignments. |

| Principal Content : | This course covers various issues in the analysis and design of the most commonly used machine components, such as: - Theories of failure. - Shafts and shaft components. - Screws, fasteners, welding, bonding and joints. - Mechanical springs. - Rolling bearings, lubrication and journal bearing. - Gears, clutches, brakes, couplings and flywheels. - Flexible mechanical elements: Belts and roller chains. |
||
| Teaching method : | The pedagogy of the course is “problem-based learning”. Approximately half of the time allocated to the course will be used in guided project work in groups. The course projects will give the students an opportunity to apply basic concepts learned in the class to real-life problems, and to learn new topics in mechanical design that are not covered in the lectures. There will be introductory and summing up lectures and the students will work in small groups with projects, problem solving, simulations and case studies. |

| Required prequisites : | Mechanics and Materials I (ME-MEM1) or equivalent. | ||
| Recommended prerequisites : | Mechanics and Materials II (ME-MEM2) or equivalent. | ||
| Relations : | The course is fundamental to the whole study program in mechanical engineering. | ||
| Type of examination : | Look under remarks | ||
| External examiner : | Internal | ||
| Marking : | 7 step scale | ||
| Remarks : | Oral examination based on a number of design projects. The final evaluation of each student will be based on an assessment of the presentation of design projects and the group report. This course is an integrated part of the study program “Engineering Design & Industrial Innovation” offered by the Department of Mechanical Engineering. |
