The problem of cantilever joint tremor of high torque robot has always affected the working efficiency of the robot.Considering the low success rate of vibration suppression due to poor signal processing ability of vibration control technology,a vibration control technology for cantilever joint of large torque robot based on big data analysis was designed.The kinematics model of the cantilever joint of the large torque robot was constructed,and the kinematics analysis results of the cantilever joint were obtained.The adaptive filter was used to obtain the working signal of the robot,and the data mining technology was used to obtain the vibration characteristics of the cantilever joint of the robot.Linear Fourier fitting method was used to design the robot cantilever joint tremor control algorithm to realize the robot cantilever joint tremor control.Application testing links were built to verify this technology.The test results show that the success rate of vibration suppression is high after the application of this technology, the problem of cantilever joint tremor can be effectively solved.
