Synchronization Characteristics of Dual-motor Coupled Driving System of Tracked Vehicle

doi:10.3969/j.issn.1000-1093.2020.10.002

Abstract

Abstract: The synchronization characteristics of dual-motor coupled driving system was researched to improve the straight driving stability of tracked vehicle. The load balancing principle of power coupling mechanism of the driving system was analyzed. It is concluded that the power coupling mechanism can reduce the load difference between the two output terminals by 60%-80% when it was transferred to the two input terminals. According to the analysis results of the factors affecting the synchronization characteristics of the dual motor coupled driving system, a relative coupling synchronization control strategy based on fuzzy PID was proposed. The simulations with and without synchronization control were carried out when there was difference in the control errors between the two motors or there were unbalanced loads at the output terminals of the driving system. The simulated and test results show that the synchronization problem of the driving system is solved by combination of mechanical and control methods.

Key words: trackedvehicle, dualmotorcoupleddrivingsystem, synchronization, straightdrivingstability
