Hydraulic Support Of Computer-aided Engineering Analysis

In order to save money, improve the economic efficiency of mining, many countries have launched research of hydraulic powered support actively. The main way to get the stress data and strain data what hydraulic powered support would show under various kinds of operating modes is to make prototype first, carry on a lot of tests that in accordance with the standard. These tests cost time and money, and have many serious deficiencies. Furthermore, some important components are difficult to carry on the test alone, thus caused certain limitation.According to the problems mentioned above, the paper puts forward that apply Computer Aided Engineering(CAE) in developing of hydraulic powered support so as to replace the traditional test, optimization design, save money, and reduce the fault designed. The method is to set up three-dimensional model with PRO/E, then Analyze it in ANSYS. It also developed a special software package through VC++ programming to make operation easy. The main content studied include: mechanics analysis of hydraulic powered support; Computer Aided Experiment of hydraulic powered support and its important components; The programming and debugging of CAE analysis software of hydraulic powered support and interface design. The main achievements are: three-dimensional modeling and space mechanics analysis of hydraulic powered support based on real structure; Development of modal analyzing module; Development of CAE analyzing module of hydraulic powered support and its important components; Development and beautification of the man-machine interface of the software package. Thus it provides abundant information for the design and developing of hydraulic powered support and its important components.Applying CAE in developing of hydraulic powered support, Using Finite Element Method(FEM), solving by computer, which can afford more overall, more accurate data of all nodal points of hydraulic powered support, and can demonstrate displacement and stress of all elements or nodal points with figure, also get more data than laboratory test. Further more, it is more faster, more economic than the traditional test, favorable to the overall optimization design of hydraulic powered support. Accordingly, the weight of the equipment and manufacturing cost can be reduced by a relatively large margin. Moreover, The friendly man-machine interface makes the software package easy tooperate, from which popularization of the software will benefit. In a word, there are important practice meaning to use the software in analyzing of hydraulic powered support and its important components.
