Dynamic calculation of the crankshaft stress-strain state

The paper describes application of the finite element method in the explicit formulation (Explicit) for dynamic calculation of the stress-strain state of the full-size crankshaft represented by a continuous model taking into account contact interaction with the supports and the rapidly varying nature of the loading. The procedure for preparing and imposing the corresponding force boundary conditions is described. The proposed calculation method makes it possible to simultaneously determine the instantaneous values of stresses due to the incoming torques and additional stresses caused by all types of oscillations (torsional, longitudinal and bending).
