Engineering Analysis Of Hydraulic Powered Support ZFS3200 Based On Finite Element Method

The hydraulic powered supports are used to assure the workspace and safety in production in modern high yield and high efficiency coal mine. Its safety and reliability determine the probability of success of comprehensive mechanized coal mining method. In order to save money and improve the economic efficiency of mining, many advanced countries that yield coal have launched research of hydraulic powered support actively. To assure the quality of design and manufacture, we need obtain the stress and strain data under various kinds of operating modes. 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, resulting in certain limitations.According to the problems mentioned above, the paper takes hydraulic powered support ZFS3200 as an example, and puts forward the application of 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. The main content studied includes: mechanics analysis of hydraulic powered support; Computer Aided Experiment of hydraulic powered support and its important components. 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. Thus it can provide 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 with 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 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.
