Abstract

Günümüz taşıt teknolojisi motor, aerodinamik, karoser ömrü, ön ve arka takımlar ile fren sistemi yönünden büyük gelişmeler kaydetmesine rağmen amortisörde gerekli teknolojik gelişmeler sağlanamamıştır. Titreşimin sönümlenmesi özellikle kırılgan malzeme nakliyesi, patlayıcı maddelerin, hasta ve yaralıların, askeri amaçlı çok özel malzemelerin taşınmasında önem kazanmaktadır. Bu makalede, amortisörün yolda karşılaşabileceği rastlantı titreşimleri, test makinesinde sinüsoidal hareket şeklinde tanımlanmış bir harmonik yöntem ile sağlanmıştır. Tipik bir otomobil arka aks amortisörü test sonuçları, literatürde mevcut çalışmalarla karşılaştırılmıştır. Bu çalışma ile harmonik ve tahmini lineerleştirme tekniği kullanılarak basit bir model amortisörün dinamik davranışının fiziksel yorumu yapılmıştır

Abstract

Despite advances in several vehicle technologies such as engine, aerodynamics, body, and break system, shock–absorber technology relatively neglected in vehicles. Shock–absorber becomes especially important in transportation of fragile materials, wounded and sick people, and dangerous military ordinance. In this study, possible random vibrations that an absorber could have were simulated by a sine wave harmonic generator. A typical car rear shock–absorber was tested and experimental data compared with the literature. Using harmonic method and estimated linearization method, a simple mathematical model that characterized the physical system was developed and model parameters also explained in this work
