“…Research work on simulation and prediction of wear has been ongoing for over three decades. Some of the early notable attempts (prior to the late 90s) to conduct computer simulation of the wear process included the works of Fries [8], Hugnell [9,10], Flodin [13-15, 18, 22], and Podra [97][98][99]. A number of these studies sought to estimate the wear in mechanical components such as cam-followers, gears, bearings, wheel-rail wear, cylinder/piston/piston ring as previously indicated (Table 1) while others explored different techniques for wear simulation and prediction on general geometries [97][98][99].…”

Kam Profillerinin Değme Analizi ve Elastohidrodinamik Yağ Filmi Kalınlığı

“…Değme alanının boyutları, değme alanı içindeki gerilmeler ve basınç dağılımı Hertz bağıntılarıyla elde edilebilmektedir. Fries ve Rogers (1988) kam ve izleyici değmeleri için basit aşınma simülasyonları oluşturmuşlardır. İzleyici devrini dikkate almamışlar ve izleyici üzerinde bir noktanın kamın bir turu boyunca karşı yüzey boyunca kaydığı mesafenin hertzien değme genişliği ile orantılı olduğunu göstermişlerdir.…”
