THE PROCESS OF 3D MODELING OF THE COMPRESSION SPRING FOR A TILLAGE ROLLER

Abstract

This article describes the process of 3D modeling of a compression spring for the design of a wave roller. Creating 3D models of structural parts is an important component in invention, it helps to save a lot of time and materials that go into creating prototypes. CAD (Design Automation Systems), such as COMPASS 3D, NanoCAD and others, allow you to create 3D models of structural parts and help to obtain the necessary characteristics of the created part or the whole structure. By creating a 3D model of the compression spring using the COMPASS 3D program, it allows you to determine its physical characteristics, which are necessary in the subsequent design of the structure of the tillage roller. This spring is designed as a part that will reduce the impact load of the roller on the soil in the contact zone with the seal due to its almost complete compression, therefore, ensuring the fulfillment of agricultural requirements for soil density. We have designed a completely new design of the tillage roller, the main feature of which are spring-loaded seals that allow for high-quality rolling of the soil with the formation of wave relief on its surface. At the same time, the design of compression springs in the Compass 3D made it possible to determine its main design parameters, such as compression force, force during working deformation, etc. It was revealed that it is necessary to install 4 springs on the roller sealer, which will allow to achieve the necessary soil compaction.
