Abstract
The ride quality has become a key component of not only design but car selling as the technology developedand the requirement of passengers grew up. Thus car industry invests lots of time and cost for the higher ride quality. The evaluation of the ride quality mainly is expressed by subjective element that drivers felt. In this paper, instead of theoriginal transfer path analysis method, relatively new methods such as OPAX(Operational path analysis witheXogeneous inputs) and OTPA(operational transfer path analysis) are used for analyzing the main hindrance element ofride quality. With those new method, contribution rate of all paths that the vibration propagate along analyzed afterdriving test on the roads having different characteristic. The comprehensive hindrance elements of ride quality arededuced from the contribution rate and the improve experiment by changing one of hindrance elements for higher ridequality.
