In this paper, a new gear dynamic model is proposed based on the real-time gear mesh stiffness (GMS). The model is validated by comparing the simulated results with experimental results, showing that it provides more reasonable predictions for gear dynamic response.
Gear mesh stiffness (GMS) is considered as one of the most important internal excitations affecting the dynamic response of the gear transmission system. In most gear dynamic model established by the lumped parameter method, the GMS is pre-calculated under static condition, and treated as a kind of known input of the gear dynamic model. However, the actual tooth contact state under dynamic operation condition is rather different from that under static condition, which means the variation of GMS should also be evaluated dynamically. In this paper, a new gear dynamic model is established based on the lumped parameter method, where the real-time GMS is used. To validate the proposed gear dynamic model, simulated result has been compared with the experiment result that reported in the literature, and it shows that the proposed gear dynamic model is more reasonable for gear dynamic response prediction.
