Systematic approach in the hybridization of a hydraulic skid loader

• Demand for efficient working machines has rapidly increased in the last years.
• Modelling and validation of an existing skid loader has been performed.
• Different hybrid configurations for the skid loader have been defined.
• A simulation tool aimed to analyse all the hybrid variants has been realised.
• A cost/benefit analysis was achieved from simulation results.

In response to growing concerns on the environment and the need to save energy, working machine manufacturers have started to consider hybridization of their products. This paper presents a systematic modelling approach to identify the most promising hybrid configurations for existing skid loaders. This approach involves accurate modelling of the existing version (fitted with a conventional power train), model validation by matching the simulation results with experimental tests, design by modelling of different hybrid configurations and corresponding cost/benefit analysis.
