NONLINEAR AND FINITE PAD LENGTH PERFORMANCE OF VEHICLE AIR CUSHION SUSPENSIONS

NONLINEAR AND SMALL PERTURBATION LINEAR MODELS FOR THE ONE-DIMENSIONAL HEAVE MOTION OF A BASIC FLEXIBLE- SKIRTED AIR CUSHION SUSPENSION ARE FORMULATED. A STUDY OF LINEAR AND NONLINEAR MODEL CHARACTERISTICS UNDER TRANSIENT GUIDEWAY AND EXTERNAL FORCE INPUTS IS CONDUCTED TO DETERMINE OVER WHAT RANGE OF CUSHION CONFIGURATIONS, OPERATING CONDITIONS AND INPUT DISTURBANCE LEVELS A LINEAR MODEL PROVIDES A GOOD APPROXIMATION TO THE NONLINEAR CUSHION MODEL. THE PERFORMANCE OF A FINITE PAD LENGTH SUSPENSION ON A GUIDEWAY CONTAINING RANDOM IRREGULARITIES IS DETERMINED. TO ILLUSTRATE THE DESIGN INFORMATION RESULTING FROM THE TRANSIENT PERFORMANCE AND FINITE LENGTH STUDY, THE PROTOTYPE DESIGNS OF SUSPENSIONS FOR INTRAURBAN AND INTERCITY VEHICLES ARE DISCUSSED. /NTIS/
