Dynamics modeling and analysis of a type of high frequency 6-DOF parallel platform

Abstract

To break the frequency band restricts caused by the transverse vibration of the actuators, a new type of hydraulically driven 6-DOF parallel platform with higher frequency band is proposed. This study presents the kinematics and dynamics of this type of 6-DOF parallel platform. Following the theoretical description of the kinematics and dynamics, a multi rigid body dynamic model is established with the Kane’s method according to a real platform which is under construction. The simulation results are shown that this platform is qualified to high frequency applications.
