Prediction and Control the Vibration of Deep Hole Processing System

Using wavelet packet achieve the reduction of the Multispan deep hole drill pipe system, effectively reduce many-degrees of freedom system.It gets a good control effect according to ER / MR damper characteristics and semi-active control theory, designs neural network controller according to intelligent control theory and proposes semi-active control algorithm that has been created the neural network of deep hole drill system. The project supported by the National Natural Science Foundation:Research straightness control of deep hole processing technology based on multi-body system theory (51175482) and National and international cooperation: Cooperative research key technologies of sophisticated and efficient deep hole machining (2013DFA70770)
