Method for Analysis of Dynamic and Strength in Internal Combustion Engine Crankshaft

Abstract:

Dynamic and strength analysis of crankshaft is the basis of structural design. The paper discussed the dynamic simulation method using software of ADAMS, at same time compared the three traditional stress analysis methods: simply supported beam or continuous beam model, single crank model and overall contact model. A new method was proposed, firstly to establish the oil film model with Reynolds equation and obtain the oil film stiffness, then to treat it as the equivalent stiffness of spring impacting on shaft neck, lastly to create the finite element model of the whole crankshaft. The model will be more precisely reflect the real conditions and can be use to the optimization of crankshaft.
