It works well or bad at work basing on its support mode, frame and some parameters. In the task,firstly, the optimal values of some parameters of the leading four-bar mechanism are determined by using Visual Basic. Secondly, ascertain the capability of hydraulic support. Nextly, the model is founded with the two-dimensional software, autoCAD , the three-dimensional software, and also do the Simulink, SimMechanics and simple analysis. Then on the base of mechanic model of support-surrounding, the mechanism and loads on the support is decided. The next work, with the condition of the design, the main mechanics of hydraulic support is analyzed and calculated by plane and spatial model. Finally, the under frame, top beam cave shield, wrists and hydraulic column are analyzed by calculation. And draw out all the process drawings. During the course of doing the paper, author not only analyses something theoretical, but also adopted a lotof actual experiences. Combining theory and practice. Therefore, the paper possesses theory and practical value, so it measures up the requiring of the nation to the undergraduate.
