In the work on the example of a tunnel erector, the concept of recurrent metamodeling is determined which allows engineering new designs of mining machines. In this case, the metamodel of their entire family is associated with the family of models of machine nodes. The effect of various laws of movement of the erector devices is analyzed and it is proved that its minimum time is observed under conditions of compliance with the U-shaped law. A mathematical model of the hydraulic drive of the erector devices has been developed, which allows, taking into account any options for moving the point mass, to determine the law of control of the movement of the spool of the hydraulic directional control valve (DCV) in relation to the laminar and turbulent type of liquid flow. The erector device metamodel was created using the algorithmic language MATLAB Simulink.
