Hydraulic transmission has a wide range of applications and attains rapid development. As the traditional methods of mathematic modeling in the design of the electro-hydraulic control system are very complex, making the design and debugging cycle of the hydraulic system longer. Thus in this paper, using the AMESim which is a senior modeling software facing engineering task design, does the modeling and simulation calculations for one kind of digital hydraulic cylinder. We get its simulation in the application of the actual working condition. At the same time, we optimize the simulation parameters and analyze the simulation results. The simulation results and analysis can provide certain reference value for the design, debugging and subsequent improvement of the digital hydraulic cylinder. According to the simulation results, it can meet different operational requirements by making appropriate compensation and adjustment in practical applications.

Traditional developments of intelligent terminal system could control only one robot and most were based on WinCE platform, which have poor versatility and expansibility. The robot hand intelligent terminal system proposed by this paper was an embedded equipment based on AT91 series chip. It had good human-machine interface with Linux system and Qt4 as software support. It adopted touch-screen technology and I2C keyboard as input device. It had two kinds of programming method, manual teaching-programming and off-line programming. The test shows that its volume is small and its weight is light to easy to operate robot handily.
