| Abstract: | In this paper,by means of FEM,the displacement and stress state of the crankshaft of a internal combustion engine were analysed,and the stress values of the crankshaft in different cylinder firing state were discussed,the influence of several factors,including every cylinder load,the installing error of the main bearing and the load distribution on the connecting rod journal, upon the stresses of the crankshaft was analysed.The reliability of the present crankshaft stress analysis method,and the correct method of computing the crankshaft stresses were discussed too. |
