Abstract

Movement of a vehicle was investigated at four degree of freedom. Modal analysis method was applied, and a program was written for calculations at MATLAB. Increase of the mass in the vehicle caused a decrease in the vibration amplitude. Since an increase of damping constant will increase damping ratio, it is almost reached to the critical damping Conductivity ratio of the vehicle is inversely related with the increase of damping ratio. While damping ratio decreases, the value of frequencies ratio reaches maximum (r=1). For the frequencies ratios greater than 1,4, the conductivity was observed below 1.

Özet

Aracın, dört serbestlik derecede hareketi incelenmistir. Modal analiz metodu uygulanmıs, hesaplamalar için MATLAB da bir program yazılmıstır. Araçtaki kütlenin artısı, titresim genliğinin azalmasına sebep olmustur. Sönüm sabitinin artması, sönüm oranını artıracağından dolayı kritik sönümlemeye yaklasılmıstır. Aracın iletim oranı sönüm oranının artısıyla ters orantılıdır. Sönüm oranı azaldıkça frekanslar oranının (r =1) değeri de maksimuma ulasmaktadır. Frekanslar oranının (r=1,4) ten büyük değerleri için iletimin 1’in altında olduğu görülmüstür.
