Aiming at crankshaft and connecting mechanism of internal combustion engine, structure is designed on the basis of mechanics analysis and strength theory. Three-dimensional digitalized virtual assembly model of the structure is built. Combined with finite element theory and ANSYS, thermodynamics coupling simulation analysis on the crankshaft and connecting mechanism is carried out. The result indicates that strength estimation problems of crankshaft and connecting mechanism could be solved through digitalized model and finite element analysis of assembly, so that development cycle could be shortened and develolament cost could be saved.
