“…As for analytical methods for defining surfaces, it is necessary to show students the possibility of their adaptation for computer implementation, without which any modern design is unthinkable. An example of such a "computer-oriented" geometry is the receptor (voxel in English terminology) method of geometric modeling, which effectively solves geometric problems of a certain class [12], [13]. We consider it very important to show the possibility of transition from graphical methods of representing objects used at the stage of creative comprehension to analytical ones, which allow determining with high accuracy their necessary engineering and geometric characteristics (position of the center of mass, trajectories of processing tools, etc.…”

This is a conceptual approach to knowledge acquisition at technical universities. The emphasis is on the consistent possession of knowledge: the acquisition of new and preservation of the existing ones. At the same time, the grapho-geometric component in technical education is one of the most important elements of fundamental (general engineering) education. It is carried out at the initial stage in the process of studying technical disciplines included in the relevant curricula. Applied geometry plays an important role in this process, and it includes such directions as descriptive geometry, analytic geometry, engineering graphics, and computer graphics that provide spatial interpretation of geometric objects and display them on a plane. This combination of subjects studied significantly enriches the geometric development within student's intellectual world.

An optimization problem of packing objects of arbitrary geometry with generalization in dimension is considered. It is proposed to use a discrete representation of objects of complex shape in the form of orthogonal polyhedra, which are compound objects obtained by combining rectangles or parallelepipeds depending on the dimension of the problem. The model of potential containers is used to form and describe the placement schemes of orthogonal polyhedra. The paper proposes algorithms that provide a qualitative increase in the speed of formation of the placement schemes by reducing the number of potential containers processed when placing each compound object. A fast algorithm for updating sets of potential containers is presented, which is based on the use of the set-theoretic operation of intersection. An additional increase in the speed of the potential containers model is achieved by removing potential containers that cannot be used to place new objects in all possible orientations. It is shown that with an increase in the number of objects placed using the proposed algorithms, the time spent on placing one object is reduced. The proposed optimization makes it possible to solve the problems of placing objects of complex shape, specified with a higher degree of detail, which will provide a denser packing in the allotted time. The results of the computational experiments carried out on the problems of packing flat and volumetric objects of irregular shape are presented, confirming the effectiveness of the developed algorithms.

“…In the process of developing an algorithm for constructing the movement of vehicles, comprehensive theoretical studies were performed [1][2][3], in which the following concepts were analyzed: basic concepts, directions of development and purpose of vehicles [4][5][6], the development of system tools in building the geometry of movement of aggregates [7][8][9], the current state of metrological support of vehicles, development trends of wheeled vehicles. As a result, the ways of building the vehicle design process were identified and the general architecture of the movement of the model version of the multi-link vehicle was developed.…”

The problem of the lack of an algorithm for constructing the movement of special vehicles is considered. The aim of the research work is to develop a software package for calculating the rotation of a multi-link special vehicle, taking into account an algorithm that describes the characteristic features of vehicle movement. The increase in the dimensions and mass of long loads necessitates the creation of new vehicle designs, the distinguishing feature of which is multi-link and long wheelbase, which in turn reduces maneuverability and requires taking into account the peculiarities of movement along a curve. To study the process of moving special vehicles, a geometric modeling method was used to develop an analytical geometric model for the rotation of the tractor and semitrailer. Based on geometric modeling, a method for determining the turning characteristics of a multilink vehicle has been developed. It is shown that patency of special vehicles is no less important quality in comparison with durability; the law of changing the ratio of the angle of rotation of the steered wheels, the various axles should provide the maximum turning moment at maximum angles of rotation of the front steered wheels, and should also ensure equality of wear at small angles.
