SIMULATION OF A RECTANGULAR THIN PLATE VIBRATION AND PRODUCED SOUND

Öz

Nowadays, many industries such as aviation, automotive and building industries use thin plate type materials. The sound radiation that these materials create in the form of vibrations also causes unwanted noises. In this study, the vibrational motion of a planar thin plate and the mathematical equations of the sound it will produce with this vibration are derived. The solution of mathematical equations of sound propagated by thin plate vibration is visualized by using MATLAB It is aimed that the model obtained can be developed and used for further analysis such as reducing the sound (noise) emanating from a vibrating thin plate.

DÖRTGENSEL BİR YÜZEYİN TİTREŞİMİ VE ÜRETİLEN SESİN SİMÜLASYONU

Öz

Günümüzde, havacılık, otomotiv, inşaat gibi bir çok endüstri ince plaka türü malzemeleri kullanmaktadır. Bu malzemelerin titreşimleri halinde oluşturacakları ses radyasyonu istenmeyen gürültülere de sebep olmaktadır. Bu çalışmada düzlemsel ince bir plakanın titreşim hareketi ve bu titreşim ile üreteceği sesin matematiksel denklemleri düzlemsel dalga denklem çözümleri ve Kirchoff İnce Plaka teoremi ile birlikte türetilmiştir. İnce plaka titreşimi MATLAB kullanılarak görselleştirilmiştir. Elde edilen modelin geliştirilerek, titreşen ince bir levhadan yayılan sesi (gürültüyü) azaltmak gibi daha ileri analizler için kullanılabilmesi amaçlanmıştır.
