Bu çalışmada ateşli silahlarda gerçekleşen geri tepmenin kullanıcı tarafından deneyimlenen etkisini azaltabilecek nitelikte biyomimetik tabanlı bir çözüm önerisi geliştirilmiştir. Bu bağlamda, ağaçkakanların kafa yapısında bulunan darbe sönümleme sisteminin ana bileşenleri yapısal analoji yöntemi ile Remington 870 model ateşli silahın kabza tasarımında kullanılmıştır. Halihazırda kullanılan orijinal kabza modeli ile biyomimetik yaklaşım kullanılarak tasarlanan modeller karşılaştırılıp, eksenel ve toplam deformasyon, reaksiyon kuvveti ve gerilme değerleri birlikte değerlendirilmiş ve silahlarda geri tepmenin en aza indirilebilmesi için kabza tasarımı ile ilgili bazı öneriler getirilmiştir.

Anahtar Kelimeler

Integration Of The Impact Damping System Found In The Nature To The Recoil Mechanism Through Structural Analogy

Öz

In this study, a solution based on the biomimetic design approach to the recoil in the firearms that users are exposed to is proposed. In this context, main shock absorption principle of the woodpecker's head was investigated and used as a source of inspiration in the handle design of the Remington 870 model firearm by using the structural analogy method. Axial and total deformation, reaction force and stress values were assessed together by comparing the original pistol grip model currently used with the models designed using the biomimetic design approach, and suggestions were brought for grip scanning to minimize the recoil in firearms.
