Development of a prototype of a torsional vibration spring damper using reverse engineering technology

Abstract

The article discusses the issues of developing a prototype of a spring damper for torsional vibrations using reverse engineering technology (reverse engineering). A spring damper with spring plates of the Austrian company Geislinger model D90/37 was chosen as the object of research. This model of dampers is widely used as part of modern marine diesel engines MAK 8M25. The issue of creating a domestic model of a spring damper is caused by a number of problems, including the complete cessation of supplies of this type of device to Russia. Spring dampers are responsible elements of machine-propulsion systems, on the efficiency of which depends, among other things, the safety of navigation of ships. On the basis of the Federal State Educational Institution of Higher Education "Astrakhan State Technical University", using a Range Vision Spectrum 3D-scanner approved by the Federal Agency for Technical Regulation and Metrology, CAT models of the components of the spring damper were obtained: an intermediate insert and a bronze spring plate. The principle of operation of the scanner is based on structured illumination and optical triangulation. Using data from the manual geometry of a real damper, as well as using the COMPASS software product, a drawing of a general view of a model spring damper of torsional vibrations was developed. Modeling (physically and using modern software products) of torsional vibration spring dampers will allow you to accumulate theoretical knowledge and practical groundwork, which will serve as the first step to strengthen Russia's technological sovereignty in the field of their design, manufacture and repair. The result of the great work done by the scientific school dealing with the dynamics of the machine-propulsion complex, under the leadership of the Honored Worker of the fisheries of the Russian Federation, Doctor of Engineering Sciences, Professor M.N. Pokusaev, will be the first domestic prototype of a spring damper of torsional vibrations.
