It is commonly recognized that characteristics of damper assembly significantly affect to vehicle dynamics. However, approach to understand its dynamic characteristics is dependent on physical testing, and effects of each component are hard to examine in detail. Therefore, the main subject of this study is to develop a method which gives easy way for designers in examining each component of damper assembly. Conventional analytical method of equivalent linear system using the restoring force model of power function type was modified and applied to damper assembly modeling. By comparison between analysis and experiment of vibration response, the validity of this modeling method was confirmed.
