This research is in association with improvement of hauling force for electric rolling stock.
In recent years, as a result of advanced high-speed train development, weight of bogie track has been decreased. As its side effect, it is considered that the weight decrease of bogie track may cause the axle-weight transfer, namely bogie track pitching. On the other hand, In recent inverter era, parallel connection of main motors has been commonly applied to electric rolling stock. However, in case that the motors are connected in parallel, the axle weight transfer and the bogie track pitching are likely to be caused, due to sudden load off of specific motor when the driving wheel slip is caused. In this study, we estimate the main motor series connection again and improvement of hauling force is aimed by applying main motor series connection. Furthemore we extended and improved automatic train operation system by PLC and used the touch panel so that we can visualize the sequence control. |
