An optimization method designed to improve 3-D vehicle comfort and road holding capability through the use of active and semi-active suspensions

摘要

The primary purpose of this paper is to analyze the effects ofvibrations on the comfort and road holding capability of roadvehicles as observed in the variation of different parameters such assuspension coefficients, road disturbances, and the seat position.This study required the development of a mathematical model tosimulate the dynamic behavior of a 3-D vehicle. With this model,various types of non-linear suspensions such as active andsemi-active suspensions may be investigated. The results obtainedfrom the simulation of the 3-D vehicle demonstrate that the use ofactive and semi-active suspension models on road vehicles prove to bebeneficial for comfort without unduly compromising road holdingcapability.
