ECTS credits: 4
Introduction to the principles of dimensioning and construction. Familiarising with the purpose and structural properties of mechanical constructions.
Basic concepts of the science of strength: load, stress, strength. Principles of dimensioning: required safety, tolerable stress, existing safety. Dimension, shape and position tolerances. Permanent joints: riveted, welded, soldered, glued, clamped. Elements of detachable joints: screws, bolts, springs. Axles and shafts. Friction and lubrication. Sliding bearings. Roller bearings. Power and motion transmission elements: belts and pulleys, chains and sprockets, friction wheels, gears. Power transmission: types of transmissions and changes of parameters per transmission degrees. Pipeline elements - tubes, shut organs. Seals and sealing.
Calculate and design simpler parts and assemblies. Analyse and apply design documentation. Identify the purpose and structural properties of parts and assemblies. Connect the parts of power transmission into a functional unit and calculate the main properties of power transmission.
Having passed the exam, the student will be able to: 1. Calculate dimensions and check the stresses of structural elements. 2. Calculate and graphically display characteristic values of tolerances and seats of structural elements. 3. Analyse the purpose and structural properties of permanent and detachable joints. 4. Analyse the purpose and structural properties of axles, shafts and bearings. 5. Analyse the purpose and structural properties of power transmission elements. 6. Calculate and define basic properties of power transmission. These learning outcomes contribute to the following outcomes of the study programme of aircraft maintenance: • 3-Classify the levels of maintenance according to the impact on safety and costs of ordinary and extraordinary maintenance. • 6-Distinguish single parts of an aircraft in relation to the physical laws of flying and functioning of aircraft systems. • 8-Make a diagram of change of the centre of gravity in compliance with the aircraft design performances, and with the operational limitations for aircraft flying and maintenance, as a result of the aircraft weighing. • 9-Calculate the necessary minimum of spare parts and materials in the warehouse for aircraft maintenance. These learning outcomes contribute to the following outcomes of the professional study programme of Motor Vehicle Maintenance: - Explain the physical parameters of motor vehicle construction. - Analyse the properties and performance of motor vehicles. - Analyse the causes and effects of vehicle malfunctions.
