Abstract

In order to improve durability and marketability of an engine and reduce the development period, crankshaft system simulation technology was developed.A crankshaft and a crankcase are modeled using the Finite Element Method (FEM). The models and a calculation model of the hydrodynamic reaction force of bearings are linked and the crankshaft behavior is calculated using numerical integration within the time domain. This simulation technology enabled accurate prediction of crankshaft behavior and stress through the high operating speeds that characterize motorcycle engines.
