Abstract
The cab vibration of large and midsize trucks during idle is a major contributor of discomfort. It is not easy to reduce vibration and typical countermeasures are costly. Those counter measures taken are mostly suspension design change related. In the past, the component parts that may affect vibration were experimented using the trial and error approach. However, changing the component parts in large or midsize trucks is time consuming. Even studies using orthogonal arrays are not efficient, either. In this paper, simulation was used with Quality Engineering approaches. When simulation is used, there is no error either due to experimental execution or measurements. Also these errors along with environmental conditions during truck operation can be easily simulated. The results of this study showed the possibility of applying Quality Engineering approaches using simulation for the reduction of vibration. A significant vibration reduction was accomplished.
