ABSTRACT The lithium plating reaction in graphite electrodes acts as a root cause for the accelerated degradation and the internal short circuits in lithium‐ion batteries. Here, an electrochemical model based on multi‐scale microstructural images was established to identify lithium plating‐stripping processes, thereby supporting the predictive outcomes

Parametric oscillations in planetary wheel gearboxes
Разработана математическая модель параметрических колебаний в планетарных колесных редукторах (ПКР) троллейбусов. Модель учитывает циклические деформации тонкостенного обода и зубьев в зацеплении эпицикла с сателлитами. Дифференциальное уравнение колебаний эпицикла приведено к виду уравнений Матье-Хилла с переменными периодическими коэффициентами.
