Abstract

Beside laminated leaf springs operate under bending moments in many engineering applications, they are also subjected to torsional loading. Factors affecting their behavior under torsional loads include friction losses between the laminates, cross-sectional geometries, the number of layers, and the way they are fixed. In this study, the torsional behavior of leaf spring systems made of AISI 1065 and AISI 1080 steel with different layer numbers and lengths was investigated by experimental, numerical and analytical approaches. An adjustable torsion testing machine of 1000 N.m capacity was designed and manufactured for spring systems with different lengths and different layer numbers for experimental study. The results obtained from numerical analysis were used to decide the spring lengths to be used experimentally, and the variation in the required torsional moment values was investigated in spring systems with different lengths and number of layers for a 0-90° angle of twist in the designed experimental set. The results obtained using experimental, numerical, and analytical approaches were compared.

Özet

Tabakalı yaprak yaylar çoğu mühendislik uygulamasında eğilme momenti altında çalışırken burulma yüküne maruz kaldıkları uygulamalar da bulunmaktadır. Burulma etkisi altındaki davranışlarını etkileyen faktörler arasında ise tabakalar arası sürtünme kayıpları, yayların kesit geometrileri, tabaka sayıları ve sabitlenme şekilleri bulunmaktadır. Bu çalışmada farklı tabaka sayılarında ve boylarında AISI 1065 ve AISI 1080 çeliklerinden oluşan yaprak yay sistemlerinin burulma davranışları deneysel, sayısal ve analitik yaklaşımlarla incelenmiştir. Deneysel çalışma amacıyla farklı boylarda ve farklı tabaka sayılarındaki yay sistemleri için ayarlanabilir 1000 N.m kapasiteli bir burulma test cihazı tasarlanmış ve imal edilmiştir. Sayısal analiz ile elde edilen sonuçlar deneysel olarak kullanılacak yay uzunluklarını belirlemekte kullanılmış ve tasarlanan deney setinde 0-90° burulma açısı için farklı boy ve tabaka sayısına sahip yay sistemlerinde gerekli burulma momenti değerlerinin değişimi incelenmiştir. Deneysel, sayısal ve analitik yaklaşımlarla elde edilen sonuçlar karşılaştırılmıştır.
