Abstract
This paper develops a parameterized substructure modeling method for planetary gear train (PGT) quasi-static finite element contact analysis. The substructure models consist of two kinds of parameterized substructure, i.e. a pair of external gearing and internal gearing with a carrier. The models can be equivalent to the overall PGT system on account of the system equilibrium and the carrier elastic deformation. What’s more, the kinematic synchronization between the substructures can be achieved due to the parameterized assembly of the models. Thus, the contact characteristic analysis of any kind of PGTs with different parameters can be conducted by using the equivalent substructure models. A spur gear planetary transmission system is taken as an example for finite element (FE) contact analysis to demonstrate the model feasibility. Comparing the results between using the substructure models and the complete model, it shows that this substructure method has enough calculating accuracy, and the calculating time is significantly reduced.
