Development and Mathematical Simulation of an Orbital-Type Actuator of a Tunneling Machine

This article is about the development and mathematical simulation of an orbital-type actuator of a tunneling machine. As a result of the research, the authors substantiated a need for developing compact tunneling machines based on hard rock destruction by the shock-mechanical method. This method allows releasing the impact energy throughout the mine face selectively and, at the same time, uniformly. The authors calculated optimum rotational speeds for actuators of tunneling machines (SQP method) for uniform load distribution on a treated surface. The article is a starting point for further development of tunneling machines equipped with an orbital shock-shearing actuator.
