Abstract

Nowadays, surface texturing becomes a significant method in the regulation of contact forces between two bodies in contact. Surface texturing is generally carried out by using elastic cylindrical beams. In this study, the effect of elastic beam array structural parameters on friction force amplitude of beams in contact with a flat, smooth and rigid body are investigated by finite-element method. For this, the frictional motion of the elastic cylindrical beam array is modeled in a finite-element based engineering software. Validation of the established model is performed. In the model, backing layer thickness, spacing distance between two beams, and number of beams are changed in elastic beam array. Normal force and friction force amplitudes in the full-sliding frictional motion of beams in contact with a smooth and rigid body are calculated. When the spacing distance between the two beams or the beam backing layer thickness is increased, the friction force amplitude decreases; and the effect of the number of beams on the friction force amplitude per single beam is negligible.

Özet

Günümüzde yüzey desenleme, temasta olan iki cisim arası temas kuvvetlerinin düzenlenmesinde önemli bir yöntem haline gelmiştir. Yüzey desenleme işlemi genellikle elastik silindirik kirişler kullanılarak yapılır. Bu çalışmada, elastik kiriş dizininin konstrüksiyonel parametrelerinin; kiriş dizininin düz, pürüzsüz ve rijit bir cisim ile arasındaki sürtünme kuvvet genliğine etkisi sonlu-elemanlar metodu ile incelenmiştir. Bunun için, elastik silindirik kiriş dizinlerinin sürtünmeli hareketi sonlu-elemanlar tabanlı mühendislik programında oluşturulmuştur. Oluşturulan modelin doğrulanması gerçekleştirilmiştir. Bu modelde elastik kiriş dizinindeki destek katman kalınlığı, iki kiriş arası uzaklık ve kiriş sayısı değiştirilmiştir. Düz ve rijit bir cisim ile temasta olan kirişlerin tam-kaymalı sürtünmeli hareketindeki normal ve sürtünme kuvvet genlikleri hesaplanmıştır. İki kiriş arası uzaklık ya da kiriş destek katman kalınlığı arttırıldığında sürtünme kuvvet genliğinde azalma meydana gelmekte olup; kiriş sayısının tek bir kiriş başına düşen sürtünme kuvvet genliğine etkisi ihmal edilebilir seviyededir
