Torsional Vibration of Unconventional Crankshaft in Four-cylinder Passenger Car Engine
Original language description
Modern internal-combustion engines have to meet demands on the overall engine efficiency which consists of particular efficiencies. The one of them is mechanical efficiency and its high value is exacted from internal-combustion engines. The reduction of friction losses of crankshaft main bearings can significantly contribute to the enhancement of this efficiency. This is the reason of development of an innovative design of a crankshaft. The potential and capabilities of computational modelling during the development of this innovative crank train is described in the paper. The dynamic computational model of the whole crank train is assembled and solved by using a Multi-Body System software, where modally reduced flexible bodies along with hydrodynamic bearings are incorporated. The paper presents the simulation results concentrated on the torsional vibration and its analysis, including concept design of a torsional damper, because a reduction of friction losses is associated with the improvement of torsional vibration in this case. On the grounds of low-costs, a rubber torsional damper is taken into account.
