| Abstract:The development process of a 9.5L engine’s crankshaft torsional vibration damper is introduced, including configuration design, torsional calculation, torsional subsidiary stress calculation, as well as the connecting performance of torsional vibration damper tap bolt. Test results show that the damper assembly’s anti-vibration performance meets with the designed index, which means it can cut the torsional amplitude of crankshaft gear system down to less than 0.15℃A, thus could guarantee the reliability of engine’s crankshaft. Meanwhile, the damper assembly’s reliability also meets with the design request. |
