Abstract
Torsional vibration (TV) is one of the major issues and very important calculation for the safe running of internal combustion engines, specifically crankshaft. The properties of parts connected to the crankshaft have significant effect on vibration of the system as well as the crankshaft life. Initial selection of this part is usually specified based on engine designer experience and also the torsional vibration calculation of the crank train. In this paper, the focus is to find optimum tuned mass to connect to the crankshaft from the damper side using CAE tools. It is a mounting disk at the free end of the crankshaft named tuned mass. Therefore, the effect of tuned mass inertia on design criteria, especially crankshaft life, was investigated. The results show high sensitivity of high cycle fatigue safety factor of crankshaft to tuned mass. Therefore, adding a suitable tuned mass to the system can increase the crankshaft life, when needed. The results were presented in the paper in detail

Summary
Torsional vibration (TV) is one of the major issues and very important calculation for the safe running of internal combustion engines, crankshaft. The properties of parts connected to the crankshaft have significant effect on vibration of the system as well as the crankshaft life Initial selection of this part is usually specified based on engine designer experience and the torsional vibration calculation of the crank train. The focus is to find optimum tuned mass to connect to the crankshaft from the damper side using CAE tools. A simulation method for torsional vibration was represented by Hafner and Maass[3], and a torsional vibration solution by Matrix method was presented by Larmi [6] In these methods, the effects of variable inertia of ICEs were ignored. The results show high sensitivity of crankshaft safety factor to parameters like tuned mass inertia and damper.
