Цель работы: анализ влияние упруго-демпфирующих характеристик двухмассового маховика ДВС на крутильные колебания деталей трансмиссии автомобиля. Задача состоит в определении характеристик вынужденных стационарных крутильных колебаний деталей трансмиссии под действием пульсаций крутящего момента ДВС. Методы: математическое и компьютерное моделирование вынужденных крутильных колебаний деталей трансмиссии. Новизна работы состоит в создании математической и компьютерной моделей крутильных колебаний автомобильной трансмиссии с двухмассовым маховиком и двойным сухим сцеплением, определении условий предотвращения резонанса крутильных колебаний маховика на холостых оборотах. Результаты: разработаны математическая и компьютерная модели для анализа крутильных колебаний автомобильной трансмиссии с двухмассовым маховиком и двойным сухим сцеплением. Проведен анализ вынужденных стационарных крутильных колебаний деталей трансмиссии во временной области. Определены условия предотвращения резонанса крутильных колебаний маховика на холостых оборотах. Показано, что использование двухмассового маховика заметно снижает СКО угловых скоростей и ускорений деталей (кроме коленвала) по сравнению с одномассовым маховиком.

The study objective is to analyze the influence of elastic-damping characteristics of the two-mass flywheel of the internal combustion engine on the torsional vibrations of the car transmission components. The task is to define the characteristics of forced stationary torsional vibrations of transmission parts under the action of torque fluctuations of the internal combustion engine. Methods: mathematical and computer modeling of forced torsional vibrations of transmission parts. The novelty of the work is in developing mathematical and computer models of the torsional vibrations of a car transmission with a two-mass flywheel and a double dry clutch, defining the conditions for preventing the resonance of the flywheel torsional vibrations at idling speed. Results: mathematical and computer models are developed for the analysis of torsional vibrations of a car transmission with a two-mass flywheel and a double dry clutch. The analysis of forced stationary torsional vibrations of transmission parts in time is carried out. The conditions for preventing the resonance of the flywheel torsional vibrations at idling speed are defined. It is shown that the use of a two-mass flywheel significantly reduces standard deviation of angular velocities and accelerations of parts (except the crankshaft) in comparison with a single-mass flywheel.
