"Machine Elements" course deals with constructions, applications and calculation methods of typical machine elements - transmissions, connections etc. "Machine elements" is the first course in curriculum where knowledge from basic courses (Technical Drawing, Material Science, Strength of Materials and similar) is used for solving real technical problems. Study course introduces with tasks of machine design and methods for solving them, as well as with literature, standards and technical means used in this field..
Goals and objectives
of the course in terms
of competences and skills
|To obtain basic design skills of machines, mechanisms and their elements by strengthening and specifying knowledge gained during basic engineering courses. To create competency in solving technical projects by developing skills in engineering analysis, calculations and elaboration of technical documentation.|
Understanding of tasks and sequence of machine design process, specifics of technical calculations. Ability to synthesize and analyze kinematical schemes of machines, to evaluate parameters of drives. - Home work, individual verification and correction of results, defence of the study project.
Skills of selection, geometry determination and strength and fatigue life calculations of transmission drives (frictional, belt, gear) and their elements (shafts, bearings). Skills to design technically well-grounded joints of machine and structural elements (welded, threaded, interference fits). - Individual verification and correction of results, defence of the study project. Exam.
Knowledge about engineering materials, standardization, factors influencing service life and technological demands of manufacturing. - Individual verification and correction of results, defence of the study project. Exam.
Ability to create constructions of machines and mechanisms, to perform sketch design, to work out assembly and detail drawings. Basic skills of computer-aided design and engineering. - Defence of the study project.
|Course prerequisites||Statics, kinematics, dynamics. Properties of engineering materials. Calculations of stresses and deformations. Projection drawing.|
