The damping or the damping forces represent certain speciality in the investigation of the internal dynamics of the transmisson systems. The special significance has this damping parameter especially in the areas of impact effects in the high-speed light aircraft and mobile transmission constructions. On the example of gear mesh in one branch of forces-flow in the presudoplanetary reducer deal the paper with some partial results of the analysis of the influence of combination damping, i.e. linear and non-linear damping, on the gear mesh dynamics.
Within the frame of the mass discretisation method has been designed the mathematical - physical model of the pseudoplanetary system of seven degrees of freedom for the analysis of the influence of the number of satellites and for free or elastic mounting of the sun wheel as a next phase of the solution of general differential system with branched - split power flow.
