Genel amaçlı sonlu eleman yazılımları sonlu elemanlar metodunun dişdibi gerilme analizine uygulanmasını kolaylaştırmıştır. Bu çalışmada ANSYS yazılımının parametrik programlama lisanı kullanılarak düz dişli çark sonlu eleman modeli elde edilmiştir. Modellemede en önemli husus çözüm bölgesinin sınırlarının tayinidir: Yazarlar literatürdeki modellerden hareketle yeni bir dişli çark sonlu eleman modeli geliştirmişlerdir. Geliştirilen model düz dişlilerde kavrama çevriminde gerilme değişiminin incelenmesi için uygundur. Çeşitli haller için analiz neticeleri grafikler ile takdim edilmiştir.

The application of finite element method to gear tooth stress analysis can be performed easily with the help of the commercial multi-purpose FEA software. In this study, the finite element model of a spur gear tooth is developed by using the parametric design language of ANSYS Software. ln the finite element modeling of gear drivers, it is important to determine the contour delimitation of the problem. The authors, adapted the contour delimitation and applied boundary conditions suggested by other researchers in literature, and proposed a new finite element gear mesh pattern. The proposed model, as shown with given illustrations, is suitable for investigations of bending stress analysis of spur gears during the engagement cycle.
