【Abstract】 In order to detect the vibration trajectory of spindle,computer vision technology,data fitting technology and motor speed closed-loop control technology are used to solve the problem that the camera shooting frame rate is not high,the camera transmission picture speed is limited and the spindle itself is not balanced.These methods reduce the requirements on the performance of the camera and the experimental mechanical platform,and reduce the measurement cost.Compared with the traditional test method,the vibration trajectory can be detected when the spindle is loaded.After testing,the high-speed spindle vibration measuring platform can be used to fit the vibration trajectory of the spindle,and the results verify the theoretical assumptions.更多还原
