| Abstract:CAE analysis and optimization design of the safety of connecting rod contact opening were carried out by using the ABAQUS and FEMFAT software. Results show that the arc-shaped design of the bottom of the connecting rod shank can effectively solve the unsafe problem of the connecting rod contact opening, and the optimized connecting rod deformation, contact stress and high-cycle fatigue strength are within the allowable range, thus meeting the requirements of safety design. This conclusion can provide an effective scientific method and reliable theoretical basis for improving the safety of dual fuel engines, and create good conditions for the installation test of connecting rods in the future. |
