Piston crank mechanism simulation using finite element method

Abstract In this paper we present the analysis of the piston crank mechanism, using the finite element method using mechanical event simulation (MES). Mechanical event simulation is a modern process of modeling and analysis of mechanical systems, much different from the classical methods known in mechanical engineering. The use of MES involves a combination of kinematics of mechanical systems, dynamics of rigid bodies, respectively nonlinear stress analysis. So, mechanical event simulation is engineering by simulating a physical event in a virtual laboratory. The crank-piston mechanism analysis has been achieved with the Simulation Mechanical program, which aimed to determine the stress state, nodal displacement or relative elongations (strains) of mechanism elements, at different time steps of the kinematic cycle, depending on the kinematic and kinetostatic parameters variable according to different curves.
