Abstract

This paper analyses the working parameter adjustment methods for hydraulic impact machine at home and abroad. An adjustment principle with distance shifted continually is first suggested in this paper. A new device with distance shifted continually on the basis of this study is designed, and the computer digital simulation is performed. A hydraulic impact machine which is controlled by computer on the basis of this study is designed. The design principles, structural feature, technical properties and control strategy are also described.
