Документ Computer and computational analisys of the biomechanics of swimming(Громадська наукова організація "Всеукраїнська асамблея докторів наук з державного управління", 2023) Lavinsky, D. V.; Adashevsky, V. M.; Druzhynin, Ye. I.The article deals with the issues of computer and computational modeling and analysis of the biomechanics of one of the most technically complex sports - swimming. Computer and computational modeling is currently an impotent part of various scientific researches. Such modeling in many cases allows either to replace full-scale experiments or to determine their rational parameters, thereby accelerating research. Computational modeling and simulation is widely used in the study of movement in various sports, which belongs to a wide class of biomechanical problems. Here, the use of computer calculations makes it possible to determine the rational parameters of an athlete's sports actions, which lead to higher sports results. It should be noted that the accuracy and reliability of computational modeling in the biomechanics of sports depend on the degree of approximation of computational schemes and models to reality. The creation of design schemes and models is impossible without the use of the results of field measurements. Based on the analysis of existing sources of information, an approach was formulated to create design schemes for studying the movement of an athleteswimmer along the distance. The systems of differential equations of motion for different stages of the distance are presented. For computer modeling, the KiDyM software package is applied, which uses the relations of the computer algebra system to construct differential equations of complex mechanical systems motion. The analysis of the presented and similar graphical information allows determining the rational values of certain parameters of the athlete-swimmer's sports actions, which allow achieving high sports results. This information allows us to adjust the technique of a particular athlete, taking into account the characteristics of his anatomy and physiology. Similar computational studies based on computer simulations can be performed for other technically complex sports.Документ Порівняльний аналіз математичних моделей процесу розгону універсальних самохідних машин(Донецький інститут залізничного транспорту Української державної академії залізничного транспорту, 2014) Самородов, Вадим Борисович; Бондаренко, Анатолій Ігорович; Кожушко, Андрій ПавловичВ роботі проаналізовані існуючі програмні комплекси, що дозволяють моделювати процес розгону універсальних самохідних машин, визначені переваги і недоліки існуючих математичних моделей процесу розгону на прикладі колісних тракторів, а також випадки їх застосування.
