Analysis of Vibration in Suspension System Using Finite Element Model

Article of Honda R&D Technical Review Vol.16 No.1


A technique enabling the level of vibration in a suspension to be predicted has been developed to improve road noise performance. Individual parts were defined and modeled to faithfully reproduce their shape and structure, and a method of assembling the parts models was then formulated to enable mid-frequency vibrations to be predicted. In addition, to enable the prediction of vibration in a running suspension, a method of experimental identifying the force transmitted to the suspension by the road surface to initiate vibration was developed. Measured values and predicted values were compared to verify the accuracy of the prediction technique. In addition, the technique was employed to study the reduction of vibration in an actual suspension, confirming its effectiveness in predicting the effects of structural change.
