Design and simulation of an electrified directional drilling machine

Directional drilling machines are meeting an increasing favour since they allow trenchless underground installation of ducts, pipes, and wires. All these underground infrastructures are quite fundamental for the development of modern urban communities. A new generation of electric directional drilling machines are proposed in this work. These electrified machines introduce specific improvements in terms of performances, functionalities, and environmental sustainability. In this work simplified models for preliminary sizing and design of the machine are introduced. Same models are also useful to improve machine calibration also exploiting data that can be easily acquired from drives of electric actuators.
