MULTY-BODY DYNAMIC SIMULATION OF LARGE IC ENGINE CONNECTING ROD

The transmission of power in IC engines are from combustion in cylinders to piston and piston pin via the connecting rod to the crankshaft which is achieved by the fluid film lubrication in the bearings. The force applied to the connecting rod is dependent on the pressure distribution in the lubricant film and by the stiffness of the connecting rod. From that conclusion, the dynamic behavior of the connecting rod is crucial for structural design. Dynamic behavior include elastohydrodynamic lubrication in bearings. In this paper, large medium speed IC engine simplified connecting rod will be analysed by modern multy-body dynamic simulation in software AVL Excite 2010.1 [1]. Elastohydrodynamic behavior of big end bearing will be evaluated. Substructuring of finite element model was done in software Abaqus 6.10 [2].
