Parameter Optimization And Adaptive Control Of Vibration Hammer

This essay introduces the principle of work for Vibratory Extracting-Driving Piling Machine .This machine which is designed can change it抯 parameter adaptively according to the ground quality.Thus the machine can work in the best state and high efficiency. In this paper four aspects are analyzed and designed effectively.First,natural frequency of the ground is estimated.based on which the vibrating frequency is changed through adapting console to generate resonance between soil and the machine;Second, the control system is designed. the vibrating frequency is adapted by control appratus on the basis of the result of parameter estimates.thus the machine can pile the column automatically .Third, the adaptive appatus for the machine frequency vibration accomplish steepless speed control. ;Fourth,machanical vibratory extracting-driving system is designed. By useing it the buiding section can save lot抯 of capital,because buiding section need not exchange the machine if the ground condition has changed and need not buy many machines to adapt the ground condition. In a word,it is very important to increase economic benifits and labour productivityfor buiding section.
