Finite Element Analysis of EA 113 Gasoline Engine Connecting Rod

Abstract

For the Santana EA 113 gasoline engine connecting rod, the motion law of connecting rod and stresses in movement were analyzed using the theory knowledge of kinematics and dynamics. Based on the finite element method, the three-dimensional model of four-cylinder four-stroke gasoline engine connecting rod was established and then the stiffness and stress distribution and strain condition of connecting rod under different working conditions were analyzed. In modal analysis and transient dynamic analysis, the frequencies of rod in resonance and the stress, displacement and velocity of connecting rod at each moment were obtained, which provide the basis for the optimal design of connecting rod.
