【Abstract】 It is difficult to determine the boundary conditions when the crankshaft strength of the multi-cylinder engine is calculated with 3-dimensional finite element method. In this paper, on the basis of the results obtained from the cutting method and continuous beam method, several models and boundary conditions are set up, which may be used to deal with the effective application of 3-dimensional FEM to the calculation of crankshaft strength.更多还原
