FORMATION OF KINEMATIC SURFACES BY THE MOVEMENT OF AUXILIARY SURFACES, TAKING INTO ACCOUNT THE DIAGRAM OF THE KINEMATIC SCREW

Abstract

The article deals with the issues of modelling a cylindrical rail surface along a given helical surface (direct problem) and (inverse problem) by the motion of auxiliary surfaces (intermediaries), taking into account the diagram of a kinematic screw. In modern mechanisms operating at high speeds, the static load is many times higher than the dynamic parameters.

The design of weapons mechanisms and military equipment with different geometric shapes, systems and their formation by movement and profiling of kinematic pairs of conjugate surfaces with the help of auxiliary surfaces (intermediaries) is proposed.

The surfaces of conjugate kinematic pairs with different parameters require the development of new effective design methods that guarantee high machining accuracy of products used in the mechanisms of military equipment and weapons and processed on automated systems. This will also expand the scope of application of modern methods of machining complex military machines and mechanisms.

Since the kinematic screw is a universal technical solution for modelling conjugate linear surfaces, this article investigates the possibility of using a parametric kinematic screw to model curved surfaces.

The solution to this problem will reduce design time and improve the accuracy of manufacturing mated mechanisms in military equipment and weapons.

Keywords: conjugate surfaces, curved surface, dynamic parameters, parameterization, kinematic screw diagram, auxiliary surfaces (intermediary), technical solutions, theoretical methods.
