| Abstract: | A new high speed hydraulic-pneumatic bar cutting machine with the radical direction clamps has been researched and developed. The large-scale hydraulic system modeling method has been introduced. By means of the large-scale hydraulic system method,mathematic model has been established. The simulation model was also constructed.The dynamic characteristics of the hydraulic system in high speed bar cutting machine have been researched.Practice has shown high production efficiency effectively improved quality of cross section by this machine. The simulation resulted in that the hydraulic system possessed better dynamic characteristics and the Large-scale hydraulic system method may be widely used for hydraulic system analysis. |
