EV, OSCILLATORY RESPONSES, ROAD SURFACES, Modeling, Multi-Body Dynamics, Non-linear DampingAbstract
The growing penetration of electric vehicles (EVs) into the automobile market presents an imperative to understand their dynamic responses to various road conditions. The study examines and enhances methodologies for modeling the oscillatory responses of EVs, particularly focusing on the unique and locally prevalent road surfaces of Uzbekistan. This geographic specificity is seldom addressed in current research, yet carries immense practical implications for the effective utilization of EVs in the region. Traditional computational models, developed predominantly for conventional vehicles, struggle to capture the distinctive dynamics of EVs arising from their unique weight distribution, torque delivery, and drivetrain configurations.
Our research introduces an advanced simulation model, employing multi-body dynamics and non-linear damping, and tailored specifically to EVs' peculiarities. The model is further refined to represent the intricacies of Uzbekistan's local road conditions, encompassing the diverse terrains and weather-induced variations. Extensive real-world data collected across the country is used for model validation, enabling more reliable and region-specific predictability.
Findings reveal an appreciable enhancement in the accuracy and reliability of EV behavior prediction on diverse local surfaces compared to standard models. These advances offer significant potential for the improved design of EV suspension systems and the development of region-specific predictive control strategies. Our work contributes to the safer, more efficient deployment of EVs in Uzbekistan and serves as a model for other regionally tailored EV dynamic response studies.
