ABSTRACT
Screw the new high-power transmission-torque-twisting shaking table is a torque testing device, which in mechanical design has a very important role. This torsional vibration vibration table can be transformed into a straight line reciprocating reciprocating swing, it requires high precision control. The hydraulic control system has a light weight, small size, long life, high reliability, stability, and control of high precision, the use of the advantages of easy maintenance, it is widely used.
This thesis on the hydraulic control system design. Through the system technical requirements and working principle of the analysis, design a system of hydraulic schematics, then the system's main parameters, and the basis of these parameters and elected a corresponding system of hydraulic components and finally the system of The checking and analysis and use of Matlab software systems analysis and simulink dynamic simulation.
Eventually the system is basically designed to achieve the technical requirements of the system, the system under normal working conditions can be achieved in all the scheduled function. Through analysis showed that the system has a very good time for the stability and response characteristics, the dynamic characteristics of stability.
Key words£o Hydraulic control system, Hydraulic servo valve, Dynamic computer simulation
