Sažetak
This paper shows workflow for analyzing crankshaft strength and fatigue due to complex dynamic behavior. Crankshafts are subjected to multiaxial stress state with variable stress amplitudes during the lifetime. Such complex dynamic behavior needs to be analyzed with multibody dynamic simulation (MBS). Crankshaft stress analyses with dynamic loadings were done with finite element method. Inputs for fatigue evaluation are stress tensors for critical crankshaft areas. Multiaxial high cycle fatigue evaluation were done with using basic unit load cases (BLCs), which are superimposed with linear static stress analysis load history, and with directly usage of displacements and rotations history from dynamic analysis. All main journals and crank pins have the same simple fillet radius. The aim of this paper is to check crankshaft fillets structural durability for infinite life. Results from both analyses are compared. Load history for nodes are displacements and rotations in time-domain for one engine cycle, i. e. 720°.
