Discussion of Lean Modelling Approaches for Powertrains of Combine Harvesters

Modelling powertrains on modern combine harvesters can become a task of enhanced complexity. The polymorphic form and branched design of both mechanical and hydraulic transmission parts make recording and modelling single power flows a significant effort. To find a practical way for modelling of principal loads on an existing machine, this paper therefore presents an alternative approach. The goal is to reduce efforts regarding measurement equipment as well as data analysis in the following modelling process. By introducing conceptual guidelines for lean modelling, an approach is presented that allows a simplified modelling of loads on powertrains of modern combine harvesting machinery. By utilizing it on exemplary machine data its potential and possible use cases are discussed.
