Short summary

In this paper, an improved mesh excitation calculation method with random cumulative pitch errors is constructed, and a lumped-parameter model for the herringbone planetary gear system is established. Subsequently, the action of random cumulative pitch errors on mesh excitations under different loads is studied. Furthermore, the dynamic mesh forces for all mesh pairs of the herringbone planetary gear system are investigated in detail, considering the effects of random cumulative pitch errors.
