Abstract

The vibrational characteristics of automotive idling and driving were investigated experimentally using various types of constant velocity joint. Plunging force (PF) and generating axial force (GAF) are the most influential quantities related to vibration characteristics of constant velocity joint. The results of the MTS test set and vibration test show that PF has higher values and GAF aggravates the automotive idling and shudder vibration characteristics. Furthermore, the variation amplitude and the harmonic periods of the vibrational characteristics in the axial direction of the shaft affect the significantly idle vibration of the drive shaft. The measured apparent mass and acceleration data are useful in calculating the PF of the drive shaft, which has no dynamic absorber.
