Abstract

The platform system includes a platform, four hydraulic supports and a unit on the platform. The motion equations for the platform system are set up as the unit on the platform is simplified as one mass element. Based on the Lowes-Hurwits stability criteria, the feedback flow coefficients of the hydraulic system are determined. Then, the Laplace transformation is used to derive the transfer function for this vibration system. The dynamic response both in the time domain and in the frequency domain for the platform system is calculated using this method. The results show that the control method in this paper is practical and reliable to the platform system.
