Abstract : The dynamic behavior of the pneumatically-suspended isolation platform at the USAF Guidance and Control Laboratory was investigated. A computer simulation model was used to evaluate the effect of changing physical parameters of the pad suspension system, and to determine the requirements for improving the present configuration. Results of this study provided the motivation for incorporating an adjustable two-way flow valve between the upper and lower air chambers. This allowed setting the damping factor at a point which would optimize pad response, so as to minimize the peak amplification of the pad transfer function. (Author)
