| description | Aiming at the realistic problems on accurate calculation of time-varying meshing stiffness in the research of multi-stage helical gear dynamics， as well as its quantitative analysis of fluctuation value， a two-stage helical gear reducer used in an electric vehicle is taken as the object. Firstly， time-varying meshing stiffness of each gear pair are calculated based on potential energy method under different helix angles <italic>β</italic>， and the parameter <italic>τ</italic> which is determined by gear parameters such as the helix angle are also calculated. Quantitative analysis shows that the smaller the value <italic>τ</italic>， the smaller the stiffness fluctuation <italic>ΔK</italic>. Secondly， a dynamics model on a two-stage helical gear system with 12 freedom degrees is established to study the dynamic characteristics of the system under different helix angles. The results show that the dynamic performance of the system is good when the <italic>β</italic> is 15°， simultaneously， <italic>τ</italic> and <italic>ΔK</italic> of gear pairs at all levels are small. It verified the feasibility and accuracy of the prediction when using parameter <italic>τ</italic> to predict <italic>ΔK</italic>， and specifically when predicting dynamic performance of the gear system. |
