When operating machines and mechanisms, they are subjected to dynamic loads that cause free, forced and parametric oscillations of the machine elements, excessive friction in the machines, unevenness of movement, creep and stress relaxation in the machine elements. This course helps the future engineer to learn evaluation technicues of the impact of dynamic loads, so that machines serve their intended time without failures, as well as to develop vibration protection systems, perform calculations of machine elements for strength, durability, stability, impact load.
