Simulation tool for dimensioning power train of hybrid working machine

Abstract

The tightening of emission standards and related regulations leads to the necessity of the hybridization of mobile machines. The working operation profile of non-road machinery differs for diverse application types and often varies on large scale. Since the series production of mobile vehicles is generally relatively limited, their design can be tailored to a specific driving cycle. Therefore, this work aims to introduce a simulation tool, which is flexible for the initial design of a non-road hybrid electric vehicle (HEV) drivetrain when different architectures (series and parallel) and dimension of components are considered. The dimensioning is based on the load cycles, that describe the power of the machine during the operational process. For the ease of the first design, each component is modeled mainly using the data available from manufacturers. Case studies are provided to illustrate the use of the simulation tool, where different options of the dimensioned hybrid powertrain are considered.
