ANALYTICAL GEOMETRY MODEL OF THE SPHERE HYPERBOLIC EXECUTIVE ELEMENT OF THE NEEDLE-SHAPED ROTATIONAL WORKING DEVICE
Methods of construction and visualization<sub> </sub>of an analytical model simulating the geometric form of the executive surface of the needle-shaped rotational working device with a complex space curving are described. The above analytical model is to be used for the parametric analysis of the process of soil interaction with the executive surface of the needle-like rotational working device.
