Elastomer Karakterli Kauçuk Burçlar İçin Otomatik Test Kontrol Ünitesi Geliştirilmesi ve SCADA ile İzlenmesi
Abstract
Elastomer karakterli kauçuk burçlar, araç parçalarının bağlantı noktaları arasında kuvveti iletebilmek, titreşimleri sönümlemek ve parçalar arası boşluğu giderebilmek amacıyla kullanılmaktadır. Burçların çok yönlü kuvvetlere ve burulmalara maruz kaldığı bilinmektedir. Bu nedenle burçlarda kauçuğun metale iyi yapışmış olması ve burçta kullanılan kauçuğun istenilen sertlikte olması en önemli özelliklerdir. Bu özelliklerin doğruluğu burca uygulanan statik testler ile sağlanmaktadır. Burca uygulanan statik test yükleri test edilen burcun yapısına göre belirlenmektedir. Bu çalışma ile burçlarda deformasyon olup olmadığı, yapışma problemi, standart yükler altında burçların esneme değerlerinin ölçülmesi ve doğrulanması amaçlanmıştır. Burç üzerine uygulanacak olan yükler, test kontrol ünitesine tanımlanmış, sensörlerden toplanan veriler yapay sinir ağlarına aktarılarak veri tabanı oluşturulmuştur. Oluşturulan veri tabanı, her bir burç için toplanan deformasyon ve yapışma verilerini kendi içerisinde karşılaştırmıştır. Karşılaştırma sonucunda deformasyon, kauçuk yapışma oranı önceki veriler ile kıyaslandığında burcun kopma değişimi %15 ve üzeri olduğunda test sistemi otomatik olarak durarak burcun gövdeden kopmasını engellemiştir.

Development of an Automatic Test Controller for Rubber Bushings with Elastomer Character and Monitoring with SCADA
Abstract
Rubber bushings with elastomer characters are used to transmit force between the connection points of the vehicle parts, absorb vibrations and remove the clearances between parts. It is known the rubber bushings be exposed to versatile forces and torsions. Because of this most important proberties of rubber bushings are adhesion on metal housing and rubbers stiffness that used on bushing. To test adhesion and stiffness some static tests performed to rubber bushing. The force that performed on static test is determined by rubber bushings characteristics. In this study, it is aimed to control the deformation and adhesion problem and verify the stiffness values of the bushings under standard loads. The loads to be applied on the bushing are defined in the test control unit, and data collected from the sensors are transferred to artificial neural networks and a database is created. The created database compared the deformation and adhesion data collected for each bush within itself. As a result of the comparison, the test system stopped automatically when the deformation and rubber adhesion rate of the bush is 15% or more compared to the previous data, preventing the bush from breaking off from the body.
