Abstract: This work presents a modeling approach of grain threshing and separation processes in axial units of combine harvesters. The dynamic model is a system of ordinary differential equations where nonlinearity enters via state transitions which we define in function of grain and straw quantities and machine settings. The model is physically intuitive, adaptive and circumventing explicit spatial dependencies. The interacting components are quantified in each of the defined compartments and, therefore, also grain threshing and separation losses can be quantified.
The model has been validated in tests with a New Holland CR unit and predicted and experimental data are compared.
