| description | As a new auxiliary energy power unit, electromechanical flywheel device based on planetary gear mechanism directly influences the power performance and economy performance of electric vehicles. The reliability, safety and economy of electromechanical flywheel device are affected by its own dynamics, mechanics, efficiency and other performance characteristics. Therefore, based on the developed planetary gear mechanism, the electromechanical flywheel device is studied in this paper. Firstly, the device topology, operating mode and other characteristics are analyzed, and the device dynamics model is established. Then, the mathematical model of high-speed flywheel stress analysis is established, and the high-speed flywheel stress and modal characteristics are analyzed. Furthermore, the loss model of the device is established, and the efficiency characteristics of the device under different states of energy (SOE) are analyzed. Finally, the influence of electromechanical flywheel device on vehicle dynamic performance and economic performance is analyzed. Compared with the original single-motor drive scheme, power performance and economical performance have both been improved. |
