Stewart 六自由度并联平台动力学模型振动分析
Vibration Analysis of the Dynamic Model of Stewart Platform with Six Degrees of Freedom
摘要
Abstract
In order to improve the control precision of the Stewart platform with 6-DOF,the methods of mechanical analysis and the rotation matrix were adopted to establish the vibration platform and the Ad-ams virtual prototype model to obtain the velocity characteristics and the acceleration characteristics.Based on the model,vibration simulation was processed under the transient motivation,and the displacement, velocity and acceleration of the upper platform were tested.The results have shown that the response of the upper platform is small and the biggest displacement appears at 0.7s and the response can be stable quickly and the first-order natural frequency is small;the platform has good low frequency characteristics and has stable response in a wide range of frequencies.关键词
