| Abstract: | A 3-D FE model of 6160 marine diesel engine connecting-rod is created. FEA on the model is carried out with a FEA software. The constraint equation and coupling are used to simulate the contact between the components of connecting-rod. The strength and stiffhess of critical areas are checked. Comparative analysis on the critical areas of the small end and displacement of big end is performed after the output of 6160 increases. |
