| Abstract: | Considering an engine crankshaft as research object,a Lumped Parameter(LP) model of Torsional Vibration(TV) in engine crankshaft system is established.The proposed LP model is then used to calculate the torsional vibration amplitude of crank nose with cylinder loads.The damping effects of crankshaft TV Absorber(TVA) are related to the moment of inertial mass of TVA about crankshaft centerline and torsional stiffness of TVA,which are analyzed later.Finally,a detailed method for determining optimal parameters of TVA is presented and the optimal results are concluded. |
