Development of Simulation Model for Series Hybrid Electric Crawler Bulldozer (SHECB) Based on ADVISOR

With the expansion of the hybrid electric technology, hybrid electric driving system is introduced from hybrid electric vehicle into construction machinery such as bulldozer. Therefore, the corresponding simulation models of hybrid electric bulldozers need to be developed firstly for further study of the new application. In this paper, through analyzing on the characteristics of crawler bulldozers, a whole vehicle module and a crawler module are created, then the relevant configuration files are modified, and finally the simulation model of series hybrid electric crawler bulldozer (SHECB) is built based on ADvanced Vehicle SimulatOR (ADVISOR).After loading an operational driving cycle of the bulldozer, a certain type of hybrid bulldozer being developed is simulated. The results show that the simulation model developed can simulate the performance of the SHECB favorably.
