Akustik özellikleri geliştirilmiş örme kumaş tasarımı

Otomobil içerisinde oluşan sesin azaltılması, otomobil endüstrisinin çok önemli bir meselesidir. Bu projenin amacı, akustik özellikleri gelişmiş örme (boşluklu) spacer kumaşların tasarımı ve üretimini yapmak ve bunları piyasada otomotiv endüstrisinde otomobil döşemesinde, tavanında ve diğer iç parçalarında kullanmaktır. Örme kumaşlar 7 fayn Shima Seiki V-yataklı düz örme makinesinde örülmüştür. Kumaşların ses yutma katsayısı ölçümü empedans tüp metoduyla yapılmıştır. Bu proje özelikle çok fazla trafik gürültüsü olan ülkemiz Türkiye için önemli bir rol oynamaktadır.

Knitted fabric design with enhanced acoustic properties

Reduction of interior noise in modern automobiles is an important issue in the automobile industry. The aim of this project is to design and produce a kniited spacer fabric having superior acoustic behavior and use this fabric to provide sound absorption in upholstery, headliners and other interior parts of automobile. Fabrics were knitted on a seven-gauge Shima Seiki flat bed knitting machine. Sound absorption coefficient of spacer fabrics are tested with impedance tube method. This project plays also very important role especially for Turkey that has high traffic noise disturbing driver.
