Abstract The article proposes an approach to synthesize mathematical models of multispeed planetary transmissions intended for numerical analysis of their dynamic characteristics under operating conditions that feature splitting and circulation of power flows (including gear shifting processes). The approach makes use of elements with spring-damper properties to model both epicyclic gear sets and friction clutches. The resulting system of ordinary differential equations has invariant structure and provides adequate calculation of the torques exerted in the elements of the epicyclic gears and the friction clutches across the entire operating range of the transmission. To verify the modeling approach, numerical experiments were conducted simulating operation of a production planetary transmission. The simulation results are presented showing transient operating modes with the friction clutches slipping and the power flows splitting and circulating.
Keywords multispeed planetary transmissions, mathematical modeling, transient modes, power circulation, power splitting, gear shifting, friction clutches
