Many cutterheads are driven by electric motors with reduction gearboxes. However, hydraulic drive solutions meet these requirements, while maintaining good efficiency for typical Tunnel Boring Machine duty cycles.
In this White Paper, after a short review of cutterhead function specifications, a design of a hydraulic direct drive (HDD) solution is described. A simulation model of the HDD solution is proposed in the last section, and the first results of performance and efficiency is presented.
