A Review on Integrated Simulation and Performance Prediction of Virtual Testing for High-speed Tracked Vehicles with Mobility-oriented Design

The mobility of high-speed tracked vehicles, as the core equipment for land assaults, is crucial for combat effectiveness and battlefield survivability. With the development of multidisciplinary collaborative simulation and virtual testing technologies, the exploration of boundary performance of equipment in extreme environments and the rapid iteration in the design stage are enable to significantly improve the research and development efficiency by constructing the virtual prototypes and environmental models and integrating the physical test elements. This paper reviews the research progress in model construction, model correction, parameter optimization and mobility prediction for high-speed tracked vehicles, focusing on system-level and vehicle-level integrated simulation and performance prediction. Firstly, the integrated simulation of mobility models and operational control models are comprehensively discussed. Secondly, the model validation methods are summarized in terms of model correction and parameter optimization. Additionally, the typical prediction methods for mobility indicators are also summarized, and their advantages and disadvantages are analyzed. Finally, addressing the developmental requirements for the virtual testing of high-speed tracked vehicles, this study proposes a mobility-oriented virtual testing architecture based on previous research, which supports the integration of complex environmental information and the iterative optimization of virtual-physical data for high-speed tracked vehicles.
