An important direction in designing hydraulic drives of mechatronic systems of self-propelled machines is research related to ensuring the stability of the characteristics of their output links (hydraulic motors) during transients. An analysis of literary sources shows that there are practically no studies of the influence of the design features of the structural elements of planetary hydraulic motors on the change in dynamic processes occurring in hydraulic drives. The paper solves the problem of ensuring the stability of a hydraulic drive’s dynamic characteristics during transient processes using passive pulsation dampers. As a result of the work done, a mathematical model has been improved, making it possible to investigate the effect of a passive pulsation damper on stabilizing the output characteristics of a hydraulic drive. It has been established that during the acceleration of the hydraulic drive, the amplitude of pressure and torque surges are determined by the safety valve’s opening time. Using a passive pulsation damper increases the opening time of the safety valve by 7 times, making it possible to reduce pressure and torque surges by 2.2 times. In steady-state operation, the pulsation damper stabilizes (smoothes) the pulsations caused by fluctuations in the disturbing external load and uneven pump delivery. Using a passive pulsation damper operating as a damping device makes it possible to stabilize the dynamic characteristics of the hydraulic drive during transients.
