In this research connecting rod is one of the most important part in engine assembly which transfers energy from piston to crankshaft and convert the linear, reciprocating motion of a piston into the rotary motion of a crankshaft. The connecting rod primarily undergoes tensile and compressive loading under engine cyclic process. The forces acting on connecting rod are:- forces due to maximum combustion pressure and force due to inertia of connecting rod and reciprocating mass. From the viewpoint of functionality, connecting rods must have the highest possible rigidity at the lowest weight. This project addresses the computation of the strength and distortion characteristics of a connecting rod. Finite element method is used to analyze the connecting rod’s stress and deformation using Ansys. For this case, a structural analysis will be performed. Ansys divides any analysis problem into three stages: preprocessing, solution and post-processing. In the first stage, the model to analyzed is imported after being designed in Solidworks in 3D and the type of finite elements are defined. In the second stage, the loads are implemented, the initial and boundary conditions are defined. The load is calculated. The axial compressive load is greater than the axial tensile load. Therefore, the design is only analyzed for the axial compressive loads. The last stage, post-processing, allows the user to view the results obtained from the analysis.

Özet:
Bu araştırma biyel bir krank mili dönme hareketi bir piston hareketini pistonlu, doğrusal krank mili ve piston dönüştürmek için enerji aktarır, motor montaj en önemli parçalarından biridir. Biyel öncelikle motor döngüsel süreci kapsamında çekme ve basma yükleme uğrar. Biyel etkiyen kuvvetler şunlardır: - maksimum yanma basıncı ve kuvvetinden dolayı kuvvetler nedeniyle biyel ve kitle pistonlu ataleti. Işlevsellik bakış açısından, bağlantı çubukları düşük ağırlık mümkün olan en yüksek sertliğe sahip olmalıdır. Bu proje, bir bağlantı çubuğunun kuvveti ve bozulma özellikleri hesaplama giderir. Sonlu elemanlar metodu Ansys kullanarak bağlantı çubuğu stres ve deformasyon analiz etmek için kullanılır. Bu durumda, bir yapısal analizi yapılacaktır. Önişleme, çözüm ve post-processing: Ansys üç aşamaya herhangi bir analiz problemi böler. İlk aşamada, analiz modeli 3D Solidworks dizayn edilen ve sonlu elemanlar tipi tanımlanmıştır sonra ithal edilmektedir. İkinci aşamada, yükler başlangıç ​​ve sınır koşulları tanımlanır, uygulanır. Yük hesaplanır. Eksenel basınç yükü eksenel çekme yükünden daha büyüktür. Bu nedenle, tasarım, sadece eksensel sıkıştırma yükleri için analiz edilmiştir. Son aşama, post-processing, analizinden elde edilen sonuçları görmek için izin verir.
