In order to simulate the multiple degrees of freedom(DOF)wind tunnel test of an aircraft,a high speed 6-DOF parallel mechanism for low speed wind tunnel tests is designed.The structural parameters of the mechanism are given by a comprehensive analysis of its requirements and restrictions.The characteristics of the parallel mechanism are analyzed.The vibration responses at the limit positions of the system are calculated by ANSYS software.At the same time,a flexible dynamic simulation for high speed emergenc...
