Abstract

A method of forming curved surfaces for weapons design software is proposed. Algorithmic implementation is based on the kinematic method of formation of conjugate curvilinear surfaces in the design of various engineering structures and weapons.
In the process of research on the basis of the kinematic method of forming curved surfaces, the optimal tolerances for the quality of surface treatment of kinematic pairs in armaments and military equipment, as well as algorithmic formations of conjugate complex curved surfaces were determined.
A comprehensive solution to this problem is important for the manufacture of products by running-in. As a result, it is of particular importance to model the accuracy of shape and size in the design of conjugated parts, especially if the shapes of these parts can only be obtained graphically.
As a result of formation of curvilinear surfaces by the offered method the parametric task of a curvilinear surface and process of creation of universal software is carried out. The created kinematic method is essentially a graphical representation of the parameters of kinematic pairs, the change of one of which leads to a change of the others, which opens the possibility of obtaining the shapes of parts with predetermined parameters. When designing conjugate curved surfaces by the kinematic method, the reproduction of their shape is adjusted as a basis for reliable operation of future real products in armaments and military equipment. That will allow to avoid undercutting, jamming, dangerous concentration of tension at processing of a product.
With the help of software and parameterization of the kinematic method, the accuracy of calculations increases and leads to an increase in the productivity of the designer in armaments and military equipment, especially if it is a guidance system. This article aims to take a certain step in this direction, regarding the creation of an algorithmic implementation of the kinematic method of forming curved surfaces for weapons design software.
