| Abstract:Based on geometry and load boundary conditions and through numerical calculation, the influence of different settings of various boundary conditions on the precision of connecting rod calculation are discussed. The results show that proper settings of boundary conditions plays an important role in precise calculation of connecting rod. These methods were applied to analyze a connecting rod for a mature type of engine and some believable results were obtained. |
