Simulation by the finite element method of The crankshaft material under the influence of the variable wind force

Abstract

This paper presents the comparison of two different approaches for crankcase structural analysis. The first approach is aconventional quasi-static simulation, which will not be detailed in this work and the second approach involves determiningthe dynamic loading generated by the crankshaft torsional, flexural and axial vibrations on the crankcase. The accuracy ofthis approach consists in the development of a robust mathematical model that can couple the dynamic characteristics ofthe crankshaft and the crankcase, representing realistically the interaction between both components. The methodology toevaluate these dynamic responses is referred to as hybrid simulation, which consists of the solution of the dynamics of anE-MBS (Elastic Multi Body System) coupled with consecutive FEA (Finite Element Analysis).
