Development and Validation of a Series Hybrid Electric Bulldozer Model on Whole Working Condition

Abstract:

Hybrid electric technology had been introduced into construction machinery from vehicle field. Hybrid electric bulldozer was focused by researchers recently. For constructing a simulation platform of the series tracked hybrid electric bulldozer on whole working condition, a model was built through the secondary development of ADvanced VehIcle SimulatOR (ADVISOR), which could simulate its performance on straight and steering working conditions. In the modeling process, bulldozer’s dynamics model, track walking mechanism model and oil pump model etc., were established and inserting by Matlab/Simulink. The field experiments were performed. The data from experiments and simulation outputs were compared to validate the correct of the model. The results showed that the operating parameters of model were in close proximity to those of experiments, which verifying the established model had significant high accuracy.
