Sensitivity Analysis of Automobile Supension System

자동차의 승차감을 고려한 현가장치의 동적 성능 해석

THe dynamic characteristics of car are determined by ride quality and control stability. These characteristics are maintained by suspension, which is composed of springs, dampers and links. The values of these parameters are very important factor to determine the dynamic characteristic. Until now, most of company depends on trial-and-error method and driving test to solve this problem. But these methods are consumed many costs and time in developing process. In this paper,to minimize these difficulties,the proper model will be developed and analyzed the sensitivity of suspension parameter in time domain. On this ground, find the design parameter that have a dominant infuence on system response and estimate the change of system response values.
