Summary:

AbstractIn current design optimization of engine crankshaft bearing, only the crankshaft bearing is considered as the studying object. However, the corresponding relations of major structure dimensions exist between the crankshaft and the crankshaft bearing in engine, and there are the interaction effects between the crankshaft and the crankshaft bearing during the operation of engine. In this paper, the crankshaft-bearing system of a four-cylinder engine is considered as the studying object, the multi-objective design optimization of crankshaft bearing is developed. The crankshaft mass and the total frictional power loss of crankshaft bearings are selected as the objective functions in the design optimization of crankshaft bearing. The Particle Swarm Optimization algorithm is used in the optimization calculation. The optimization results are compared to the ones of original engine design and the single-objective design optimization of crankshaft bearing. The results show that the total frictional power loss of crankshaft bearing and the crankshaft mass are decreased respectively by 26.2% and 5.3% by the multi-objective design optimization of crankshaft bearing, which are more reasonable than the ones of single-objective design optimization in which only the crankshaft bearing is considered as the studying object
