| Research Abstract |
The suspension spring vibration of a truck is generated by the road roughness at the expansion joints, when the truck run a highway bridge. Moreover, the spring vibration of a truck and bridge vibration transmits to the houses around the bridge. In this study, in order to reduce these vibrations, the relation of the road roughness round the expansion joints and the suspension spring vibration of a truck were investigated. Also, this study proposed a new evaluation method for detecting the road roughness with the long wavelength affecting trucks. The validity of the method was verified for the various roughnesses which had caused the vibration problem.
