Description

Technical field

The invention relates to methods for obtaining parallel-perpendicular spherical systems that can be used to assemble three-dimensional objects representing the intersection of several planes, and can be used when assembling structures in mechanical engineering, construction or other fields of technology.

State of the art

A method for assembling three-dimensional objects is known from the prior art, in the process of which planes are formed from two wire meshes, while the first wires with helical winding, which run parallel to each other through their axes, are twisted with each other in the x direction in such a way that two adjacent the wires are connected through an intersection point per turn, and in the transverse direction relative to the axes of the first wires, a plurality of helical second wires, which run parallel to each other through their axes, are twisted into the first wire mesh of the first wires and form a second plane of two wire meshes, while performing offset in the z-direction relative to the plane of the aforementioned wire meshes, twisting a plurality of helical third wires running parallel to each other by means of their axes crossing each other, and the second wires of the plane being perpendicularly offset with respect to them, thus that each second of the second wires of the plane is crossed and the first wire mesh is formed in the second plane in the transverse direction relative to the axes of the third wires, while a plurality of helical fourth wires are twisted, passing parallel to each other through their axes, and to form the second wire mesh in the second plane these fourth wires intersect at their intersection points with each other and with the intersection points of the third wires of the second wire mesh to form an intersection point (see RF patent No. 2508175, published on February 27, 2014 IPC B21F 27/12). The disadvantages of this solution are the difficulty of assembling three-dimensional objects, as well as high material costs and the impossibility of using materials other than wire, in addition, the three-dimensional object obtained by this method does not have the necessary rigidity. The proposed solution is aimed at eliminating these shortcomings.

The technical result achieved by implementing the proposed method is to simplify the assembly of three-dimensional objects, as well as to increase the reliability of three-dimensional objects obtained using it.

The essence of the invention

To eliminate the shortcomings of the prototype, as well as to achieve the proposed technical result, a method was developed for obtaining parallel perpendicular spherical systems, including the following operations: a) select at least six identical elements; b) determine at least one connection point on the first element; c) determining at least a connection point on the second element; d) connect the elements at certain connection points in such a way that the planes passing through the first element and the second elements are perpendicular; e) select the next element; f) determine its points of intersection with the previous elements; g) connect the element with the previous elements at the intersection points in such a way that the planes passing through the elements are mutually perpendicular; the element is parallel to the fourth, the second element is parallel to the fifth, and the third element is parallel to the sixth element.

The elements can be ring-shaped, made in the form of a flat circle or square. The elements can be made of metal and connected by welding. The elements can be made of polymer and connected with glue. The elements can be made of composite material.

In addition, a three-dimensional object is proposed, obtained using the proposed method, containing at least six intersecting planes.

Implementation of the invention

The proposed method is implemented as follows: first select at least six identical elements, then determine at least one connection point on the first element; then determine at least the connection point on the second element; then connect the elements at certain connection points in such a way that the planes passing through the first element and the second elements are perpendicular; then select the next element; determine its intersection points with the previous elements; then the element is connected to the previous elements at the intersection points in such a way that the planes passing through the elements are mutually per-

are perpendicular to the following elements. To attach the remaining elements, repeat the operations associated with determining the intersection points on the previous elements of the operation and attaching them to the already assembled structure until all the elements are installed in a three-dimensional object, while fulfilling the condition that the first element is parallel to the fourth, the second element is parallel to the fifth, and the third element is parallel to the sixth element, and each element is fixed at two points. Performing such operations of the method, as shown by experiments, a three-dimensional object is obtained, which has high strength properties, due to the intersection of planes passing through the elements of the object at right angles. In addition, the very method of assembling such an object is quite simple, since it contains the repetition of several simple operations. When implementing the method, elements of various shapes can be used depending on the field of application of the obtained three-dimensional object, for example, for assembling propellers for swimming facilities, the shape of the element can be a flat round plate. In other cases, the elements may be annular, made in the form of a flat circle or square. In this case, the material and method of connecting the elements is also selected depending on the scope of the three-dimensional object assembled by the proposed method. Therefore, the elements may be made, for example, of metal and connected by welding, or the elements may be made of polymer and connected, for example, with glue. In addition, the elements can be made of a composite material. Moreover, each element of a three-dimensional object can be made of a material different from other elements. Consider one of the possible options for implementing the proposed method, choose six elements representing a two-dimensional figure - a circle, and divide each of them into three parts, the areas of which are equal, while two parts are segments of this circle. The division points of these parts are marked (see Fig. 1) and all 6 elements are connected in series (see Fig. 2) through the marked points so that the planes passing through the elements are perpendicular to each other, while fulfilling the condition that the first the element is parallel to the fourth, the second element is parallel to the fifth, and the third element is parallel to the sixth element (see Fig. 3), and each of the elements is connected at two points to the other elements. In this case, a variant of the implementation of the method is possible, in which the elements are connected into separate two groups of 3 elements, which are further connected to each other at the marked points. If it is necessary to connect more than six elements, the sequence of actions of the method does not change, but additional elements are added in pairs, while changing the connection angle between the planes at their connection point. If two-dimensional figures are used as elements, then it can be a circle, a square, if three-dimensional figures are used as elements, then it can be a torus, cubic shapes, triangular shapes. At the same time, it should be understood that the choice of the shape of the figure is determined by the scope of the obtained three-dimensional object, and not by the requirements of the operations of the method for obtaining it. As the material from which the elements are made, materials can be used, the strength properties of which correspond to the field of application of the obtained three-dimensional object, for example, metals, metal alloys, plastics, elastic materials. The invention has been described above with reference to a specific embodiment. For specialists, other embodiments of the invention may be obvious, without changing its essence, as it is disclosed in the present description. Accordingly, the invention is to be considered limited in scope only by the following claims. CLAIM 1.
