Course Objectives 1. To introduce the analysis phase and machine elements in mechanical design.
2. To develop mathematical models for functional analysis and stress calculation of machine elements by using engineering sciences. By using the available experimental models determine the input and output values of the machine system elements.
3. To use the standards and design criteria.
4. To improve the goal recognition, creativity and intuition and also to enable the students to gain experience in machine design.
5. To provide the necessary knowledge and capability for task spesification, consept formation and synthesis phases of the machine design. To develop the further stages of the machine design; manufacturing of prototypes, testing and marketing.
Course Description Course Description

Mechanical engineering design activity and importance of machine elements knowledge in this activity. Fundamentals of design and applications of machine elements. Welded, soldered, adhesive bonded, riveted joints. Shaft-hub connections. Bolted joints and power screw mechanisms. Pins, knuckles, springs, shafts and axles, coupling and clutches, lubricants and lubrication theory, sliding and rolling bearings.
Course Outcomes At the end of this course, students should be able to:
1. Recognize formation and calculation welded, soldered, adhesive bonded and riveted joints.
2. Recognize machine elements which are used in form and force connected shaft-to-hub connections and their standards. Recognize the formation and calculation methods of the keys, splined and profiled shafts, pin joints, press and fit joints and friction-joints with intermediate parts.
3. Recognize the design and standards of the pins and knuckles.
4. Recognize bolted joints, power screw mechanisms and screw thread forms and their standards, screw mechanics, calculation of stresses in bolted and screw joints and their determination of dimensions, and also known the design of preloaded bolted joints.
5. Recognize the elastic behaviour of materials, application areas of springs and their properties, and also know the designs of the flat, leaf, helical and special metal and rubber springs.
6. Recognize the types and standards of axles and shafts and their stress, deformation and vibration calculations.
7. Recognize the types, characteristics, application limits, dynamic behaviours and heat balance of the couplings and clutches.
8. Recognize lubrication; friction and wear, lubricants and their characteristics, viscosity, the effects of temperature and pressure, additives.
9. Recognize the lubrication theory, form of load-carrying films and Reynold’s differential equation.
10. Recognize the sliding bearings; define the types and load carrying ability and calculation of bearing temperature of the external pressed thrust and journal bearings and also hydrodynamic thrust and journal bearings.
11. Define types and standards of rolling bearings and determination of their bearing dimensions under static and dynamic loads. Recognize Stribeck and Palmgren-Eschmann equations. Basic load rating, basic life. Bearing selection under variable loads and variable number of revolutions. Statistical characteristics of bearing lives.
12. Select machine elements by means of tutorials and homework. Determine the dimensions of the machine elements by using strength of materials calculations. Understand application of standards and design criteria of the machine elements.
