Crank System Coupling Simulation between Dynamics of Flexible Multi-Body and Hydrodynamic Lubrication 2007-01-3484

A flexible multi-body system dynamics model of crank system is established based on MSC/ADAMS with the purpose of modeling the crank in internal-combustion engine accurately. The film hydrodynamics model is built up through linking ADAMS and elasticity hydrodynamics subroutines. Coupling analysis between multi-flexible body system dynamics and hydrodynamic lubrication of crank system is processed. Results between the model with the function of film and without the function are compared. Then the journal center loci are given. The effects of different factors such as pressure, temperature, rotating speed and load on the journal center loci are also analyzed.
