Abstract
This paper optimizes the combination of design parameters for improving the kinematic characteristics of a midsize truck using both design of experiment and computer simulation A computational model of the front suspension and steering system of a midsize truck is developed for analyzing kinematic and compliance characteristics A taper leaf spring is modeled as a flexible body using finite elements A bump mode test is performed to validate the reliability of the developed computational model Mean absolute values of the toe angle and wheel base change are used as objective functions Modifiable hard points are selected as design parameters An optimal combination of design parameters for improving kinematic characteristics is suggested based on analyses of variance and factor effects using a table of orthogonal arraysBo Myung Kim received his BS degree in Aerospace Engineering and MS degree in Precision Mechanical Engineering from Chonbuk National University Korea in 2003 and 2009 respectively He is currently a researcher at KDC Co in Sacheon Korea Mr KIM’s research interests are in the area of vehicle dynamicsChae Youn Oh received his BS degree in Mechanical Engineering from Chonbuk National University Korea in 1982 He then received his MS degree and PhD in Mechanical Engineering from Iowa State University USA in 1987 and 1990 respectively He is currently a Professor at the Division of Mechanical System Engineering at Chonbuk National University in Jeonju Korea Dr OH’s research interests are in the area of vehicle dynamics and haptics
